Mass measurement is all around us, and it’s something that children should learn early. This will help them effortlessly grasp physics concepts later in school.

The first thing to understand is that mass is not the same as weight. Your weight changes depending on where you are — your body is heavier when curled up on the couch than when stretching as high as you can.

The metric system

The metric system is the measurement system used by most countries. It is also the system of choice for scientists and engineers. It is a decimal-based system that uses multiples of 10. This makes conversions between metric units relatively simple, even down to the smallest unit, the gram.

The meter is the base unit for length, the kilogram is the base unit for mass, and the litre is the base unit for volume. Each of these base units has derived units (for areas, densities, temperatures) that are built on them.

There are twenty-four metric prefixes (kilo-, hecto-, deka-, centi-, and deci-) that can be combined with these base units to form other metric units. The metric system is often thought to be difficult because of all the different units and symbols that it has. However, it is very easy to use if you take the time to learn it. Using a metric tape measure, measuring objects in metric units, and weighing yourself on a metric scale are good ways to get started.

The kilogram

When measuring something, we want to know the exact amount. So we use scales. But it turns out that scales aren’t always accurate enough. For some applications — such as testing medication, developing new materials or analyzing the environment — we need to be able to measure to parts-per-billion accuracy. This is why scientists decided to redefine the kilogram in November 2018.

Instead of comparing the gravitational force on an object to that of a golf-ball-sized metal artifact called Le Grand K, which lives at the International Bureau of Weights and Measures (BIPM) in Sevres, France, we will compare it to a precise value of a fundamental constant of nature.

It is a move that will end the era of human-scale physical objects defining measurement units like length, time and mass. It will also set the stage for a future in which all seven SI base units — the meter for distance, the second for time, the kilogram for mass, the mole for amount of substance, the ampere for electrical current and the kelvin for temperature and luminosity — are defined by comparison to a single, fundamental constant of nature.

The meter

The meter is the key to accurate mass flow measurement. This measure differs from volumetric flow rate, as it identifies mass per time rather than fluid volume. It is used in many critical applications throughout industry, including recipe formulation, material balance determinations, billing and custody transfer operations.

The Coriolis meter is one of the most accurate mass flow meters available for clean or corrosive gases and liquids, especially in supercritical applications. This gyroscopic meter utilizes motion mechanics to directly measure mass flow, density and temperature.

The meter’s sensor tubes are separated by a splitter with drive coils installed in the middle and detection coils at both ends. When excitation power is applied to the coils, they induce vibration in the sensor tubes that produce a twist in the tube deflection (spring torsion) proportional to the product’s mass flow. This two-tube design reduces external vibration interference and the amount of power required to initiate tube vibration. However, the thin-walled sensor tubes are susceptible to degradation from pitting, cracking, coating, erosion and corrosion that cause shifts in the meter calibration factor over time.

The second law of thermodynamics

Most physical laws take the form of an equation that describes precisely what must happen in a particular situation. The second law of thermodynamics, however, is an inequality that imposes additional restrictions on processes.

It states that all processes that involve the transfer or conversion of energy cannot be truly reversible. This means that in a closed system, the average entropy of that system must always increase, as is evidenced by friction and other irreversible phenomena.

While the Second Law may seem inconvenient, it is essential to life on Earth. For example, in order for the proteins and nucleic acids that make up a human cell to be able to function properly, they must be assembled from much smaller molecules such as amino acids and nucleotides.

This assembly process requires heat, which is an increase in the entropy of the surrounding environment. Thus, the formation of a protein or nucleotide requires that energy be transferred from the surroundings to the new molecules. Inevitably, the entropy of the surrounding environment will therefore increase by an amount equal to the heat energy transferred.

Getting accurate and consistent weighing results requires careful attention to detail. For example, a chemical sample should never be added directly to an analytical balance. Instead, it should be weighed in a tared container.

Process weighing uses advanced controls and scales to measure and dispense precise quantities of materials into tanks, bags, or hoppers. This helps reduce waste and improve production.

Accuracy

For process weighing, accuracy is crucial to ensuring that your measurement data meets the specified tolerances. However, it’s important to remember that accuracy is not a standalone specification and is actually a combination of several specifications such as repeatability, linearity, resolution and response time.

Keeping your balance in the best location for accurate readings can help to minimize errors that affect measurement results. Ideally, your balance should be situated in an area that is protected from vibration and has minimal exposure to external factors such as temperature, humidity, and magnetic or electrostatic fields.

Careful handling of your samples and use of forceps or gloves to handle small weights can help to reduce the likelihood of fluctuations that can cause inaccurate results. Using the right sensitivity weights for your application can also help to ensure that your readings are as close to the true mass of the object being weighed as possible.

Efficiency

Weighing equipment can become inefficient if not optimised regularly. From preventative maintenance and calibration to data integration and operator training, there are many ways to improve weighing efficiency and performance.

Using anti-static bars and sample management software reduces the chance of small amounts of material being lost during dispensing. But this is not a complete solution, as even with these tools, tiny particles can get into vials over time and impact the accuracy of your results.

Process weighing systems help to make your operations more efficient by automating the material tracking process. Whether it is a payload management system that lets your machine automatically fill to its optimum capacity or a set of scales integrated with your control systems, these solutions allow you to track material without having to stop and manually count by hand. This gives your operators more time to work and also ensures consistent, high-quality batches. Plus, your data stays accurate in the case of power outages or temporary signal weakness.

Safety

Precise weighing ensures that ingredients are added in the correct order and proportion, maintaining consistency and quality. This reduces product waste and raw materials losses, and helps manufacturers maintain high standards that boost profitability.

Safe weighing practices start with understanding the chemical being measured, including its volatility, reactivity and toxicity. The appropriate PPE is worn (gloves, head cover, face mask), and specialised containment tools like fume hoods, safety cabinets and glove boxes limit exposure to harmful chemicals.

Weighing equipment must be carefully selected to suit the environment, and regular maintenance and calibration are vital to ensuring accurate measurements. Corrosion-resistant designs and materials protect sensitive instruments, while automated temperature compensation and washdown systems preserve performance in extreme conditions. Weighing equipment used in hazardous areas must be intrinsically safe, complying with standards like ATEX to prevent accidental sparks that could ignite explosive vapors or dust. Keeping the environment stable is also critical, with routine ventilation and avoidance of drafts.

Compliance

Precise weighing processes contribute to compliance by lowering raw material losses and rework. This cuts production costs while boosting profits. In addition, a high level of accuracy minimizes employee exposure to hazardous materials and prevents accidents.

Depending on the industry, specialized automated systems might be required for specific applications. For example, pharmaceutical companies prioritize weighing ingredients for manufacturing with high precision to ensure the final medication meets strict quality standards.

Another crucial aspect of ensuring compliance is regular balance validation. This involves comparing the instrument to standard calibration weights that have known calibration values. To avoid errors, it is important that the instrument and the calibration weights be in thermal equilibrium prior to a mass calibration. COOPER Instruments can provide various methods to solve your in-process weighing challenges, including utilizing weigh modules that convert tanks and hoppers into complete batch weighing systems or turning conveyor sections into checkweigh stations. We can also supply local displays with PLC connectivity, DIN rail mount units, and panel mount units.

Many people try to control their weight by eating more nutrient-rich foods, such as vegetables and fruits. Some of them also try to avoid foods and drinks that are high in calories, salt, sugar and fat.

They may also try to eat more healthy fats, such as those in avocados, nuts and olive oil.

Eat More Vegetables

Vegetables are a valuable ally in the fight against weight gain because they’re naturally low in calories. One serving of vegetables (about 1 cup raw or 1/2 cup cooked) contains only about 25 calories, so adding more veggies to your diet can help you cut down on unnecessary calories without sacrificing flavor.

Veggies also provide your body with a variety of nutrients. In fact, researchers found that a diet high in veggies may protect you from conditions like heart disease and cancer, and improve your overall gut health.

Getting more vegetables into your diet doesn’t have to be difficult or expensive. Start by keeping frozen vegetables in your freezer so you always have a healthy option on hand when you need it. And try to avoid cooking or eating them with sauces, syrups or high-fat dressings because these add extra calories. Instead, steam, roast or grill veggies to get the most flavor out of them.

Cut Back on Carbohydrates

Carbohydrates provide energy that fuels the body’s cells, muscles and organs. However, too many carbohydrates can cause weight gain by adding excess calories to the diet.

Refined carbohydrates are known for sending blood sugar levels on a roller coaster ride, which can trigger food cravings and increase hunger. Instead of reaching for processed foods, choose complex carbohydrate foods such as whole grains, beans and high-fiber vegetables like sweet potatoes and mushy peas.

Also, try to cut back on sugary drinks. Swap soda for water, tea or a non-sweetened fruit juice. Then, add protein and healthy fats to your meals to feel full. Protein slows digestion and doesn’t raise insulin, unlike carbohydrate-rich foods. Additionally, some studies have linked low-carbohydrate diets to weight loss and reduced risk for heart disease. However, other studies have shown that long-term carbohydrate restriction can lead to health problems including low blood glucose, muscle loss and nutrient deficiencies. Therefore, it’s important to talk with a registered dietitian to find the right balance of carbohydrates for your individual needs.

Eat More Healthy Fats

Fats should make up 20-35% of your total calories, but the type of fat matters. Aim for unsaturated fats such as those from olive oil, avocados and some nuts and seeds. These healthy fats supply essential nutrients that your body can’t produce on its own, including omega-3 and omega-6. Avoid unhealthy fats, which can raise your cholesterol and increase your heart disease risk, such as trans fats and saturated fats found in fatty cuts of meat, full-fat dairy like whole milk and cream and processed foods. Each gram of fat provides 9 calories, so limit how much you eat. iStockphoto/AdrianaMcGraw.

Inquisitive children are ready to learn at any age, and early exposure to physics concepts like mass can help them effortlessly understand subjects like mathematics and chemistry later. Mass is a property of matter that doesn’t change if the body changes shape or location.

A balance is the most common device for mass measurement, and it works in locations with and without gravity to measure objects equally.

Definition

Mass is the amount of matter in an object or particle. It is the most fundamental property of matter, and it does not change.

Measuring mass is usually done using a balance. An unknown mass is compared to a known value of mass and the difference between the two is the measured mass. Balances can be used in places with gravity or without it since changes in the strength of the gravitational field affect both masses on the balance equally.

The terms weight and mass are often confused. However, they are different physical properties. Weight is a measure of the effect of gravity on something, while mass is a measurement of the amount of matter that something has. An elephant and a mouse may be the same size, but an elephant has much more matter inside it than a mouse, so it has more mass. This difference in matter is why a person’s weight may differ when they go to another planet: the gravitational force is different, but their mass remains the same.

Units

The unit used to measure mass is the kilogram, kg. It is part of the metric system and is also commonly used in non-metric systems, such as the avoirdupois pound (used in the United States Customary and Imperial systems of units).

The kilogram along with the meter, second, ampere, kelvin, and mole are known as SI base units. The base units are defined in terms of the physical quantity of the International Prototype Kilogram, a golfball-sized platinum-iridium cylinder kept at NIST.

Other units for quantities like the liter for volume are called derived units because they are obtained by multiplying or dividing the SI base units. Derived physical quantities are also defined in terms of these units. A coherent system of units is one where the base units and derived units are consistent with each other. In such a system, 1 kilogram is equal to 1 kilogram per square centimeter. This page is based on a Wikipedia article, and as such it may not have been reviewed by professional editors.

Calculation

While the terms “weight” and “mass” are often used interchangeably, they refer to different measurements of heaviness. Mass is a measurement of the amount of matter contained in an object, while weight is based on the gravitational force that objects exert on one another.

In order to calculate an object’s mass, you must first have information on its density and volume. Density is the amount of matter per unit area and can be found through a formula, such as mass = density / volume. Volume is the amount of space an object occupies and can be measured in units like cubic meters i.e. m3 for solids or cubic centimeters i.e. cm3 for liquids.

The most common method of measuring mass is using a balance. This allows you to compare the unknown object’s mass to a known value of an existing sample, eliminating variables such as gravity. Balances are expensive and delicate instruments, so they must be treated with care.

Interpretation

The interpretation of mass measurement requires consideration of the statistical background. The normal distribution of mass data is not always appropriate, especially for very small or varying samples. A good understanding of this is crucial for the use of statistical tests and for the evaluation of precision, which is a function of sample variability.

Mass spectrometry literature often uses a number of terms that describe the statistics of accurate mass measurements. This confusion can lead to misunderstandings. A good source of information is the IUPAC definitions and descriptions of terminology used in mass spectrometry.

The most basic concept of matter is that it has mass. But a greater amount of matter does not necessarily mean a greater weight (although it will). Rather, an object’s mass is determined by its density and volume, and it is its acceleration — observed when it is subjected to the force of gravity — that determines its weight. The same principle applies to a weighing scale.

Precise weighing processes reduce rework and raw material loss, boosting profitability. Automated weighing systems also eliminate safety risks by handling and transferring masses in closed environments.

Accurate weighing requires good laboratory techniques and practices. It also relies on having a consistent weighing process. This is important for achieving repeatable results and meeting product quality standards.

Accuracy

Whether the process is weighing raw materials on a receiving dock, filling and labelling finished goods’ boxes for inventory, or checking product consistency on an assembly line, the weighing process requires a precise measurement. Any errors or omissions in this critical step can result in costly mistakes that can be difficult to correct.

Fortunately, there are several steps you can take to ensure that your process is accurate. Using an OIML or NTEP approved balance that has been properly installed and calibrated is one important first step.

Moisture can wick into the junction box and interfere with the signal lines to the load cells, decreasing accuracy. For this reason, it is best to use a waterproof NEMA 4-rated junction box and plug unused junction box holes. Finally, it is best to keep your weighing system in its rated temperature range.

Errors

Weighing errors often occur as the result of many factors that are difficult to control. This makes it important to use a dedicated sample management or LIMS software that provides a streamlined testing regime that meets your scientific requirements without taking up your whole working week.

Human errors are common and can happen despite the best efforts of alert and careful operators. Fingerprints on the rim of the container, oily fingers or residue on a lid can all add mass and alter readings.

Temperature changes also contribute to weighing errors. This is why it is critical that the balance, reference standards and test objects are in thermal and environmental equilibrium before the mass calibration starts. This is why each mass SOP includes instructions that the weights and balance should be allowed to equilibrate for 24 hours before starting the weighing.

Safety

Using accurate weighing methods, companies can reduce their exposure to risk, ensuring product quality, operational efficiency, and regulatory compliance. This involves choosing precision instruments, establishing standard operating protocols, and regular calibration and maintenance schedules.

Pre-weighing ingredients or components prevents over- or under-estimating the quantity needed. It also helps ensure that all ingredients are added in the correct order and proportion, preserving the overall quality of the end-product. In manufacturing, this is particularly critical for the pharmaceutical and food sectors where precise ingredient weighing can save time, money, resources, or even lives.

The weighing system must be capable of supporting the combined weight of both the container and the measured sample to avoid damage and ensure accuracy. Additionally, the weighing system should be inspected and calibrated at regular intervals to account for environmental changes that can affect measurement uncertainty and minimum weight. The weighing equipment should be placed in an area with minimal vibration to prevent interference with the load cells’ output signal.

Repeatability

Generally speaking, repeatability is the ability of a balance to return the same result for the same object under the same conditions. This differs from accuracy, which is the weighing instrument’s ability to measure an object within its permissible error limits (see Figure 1).

In many applications it is important for the repeatability of a weighing process to be close to zero. However, this depends on the application and the user’s weighing needs.

A balance should be exercised before taking readings to increase the repeatability of its measurements. This is done by placing a weight equal to the load that is to be measured and then arresting or removing it from the pan. This allows the balance to “warm up” and eliminates some of the larger variations present in initial weighings. Good Weighing Practice recommends that all balances be exercised ten times before performing routine testing. The four significant contributors to measurement uncertainty are identified by the GWP standards as: (U_tot is total measurement uncertainty; U_RP is repeatability; U_EC is eccentricity; and U_NL is nonlinearity). Each of these contributes to a different part of the overall tolerance limit.

A person can control their weight by focusing on the types of food they eat. They should also consider their daily activities. This can help them maintain a moderate body weight.

Some medications and certain health conditions can cause people to gain weight. They may also need to find ways to cope with unintentional or intentional sabotage from friends and family members.

Portion control

Portion control involves managing the amount of food you eat at each meal. It can help you maintain a healthy weight and achieve your health goals. There are several strategies you can use to practice portion control, including using portion-control plates and keeping a food diary. However, it is important to remember that the goal is not to restrict food, but to balance your diet.

Eating nutrient-dense foods like fruits, vegetables, lean proteins and whole grains can help you manage your appetite and calorie intake. It is also helpful to eat mindfully and pay attention to your hunger cues. In addition, it is important to read food labels to understand serving sizes and calorie counts. Visual cues can also be helpful, such as the size of your hand or a salad plate. You can also try to eat smaller meals and fill up on low-calorie, high-volume foods like vegetables and salads. You should avoid eating processed foods, as they are often higher in calories and can lead to overeating.

Eat healthy fats

Achieve a healthy weight by replacing unhealthy fats with healthier ones, such as monounsaturated and polyunsaturated fats. These fats are found in foods such as avocados, olives and nuts. You can also find them in oily fish like sardines, mackerel and salmon, rapeseed and canola oils, as well as in whole milk and cream. However, remember that all fats are high in calories, so watch your portion sizes. One ounce of nuts is about 160 calories.

Scale is a term that evokes a wild array of images. It is the diminutive, Lilliputian or mini size of a thing that distinguishes it from its full life size.

It is also the basis of economies of scope, a characteristic that drives superlinear growth when inputs decline relative to outputs. The process of scale construction involves the identification of a domain and item generation.

Definition

A scale is a series of intervals that ascends or descends. Examples include a musical scale of do-re-mi-fa-so-la-ti-do, or the graduated line on a map that represents proportionate size.

Scaling differs from growth in that it involves repeated exponential increases in the size of a system over time, rather than just a one-time increase in a fixed amount. From a mathematical perspective, scaling is characterized by the formula y = aebtwhere a and b are constants, x is the base of the logarithm and t is the time.

While the number of different scales is theoretically infinite, particular scales tend to become conventionalized within any given culture or musical tradition, making them characteristic of that tradition’s tone system. In addition, simple scales often display a narrow range of pitches, with large skips between pitches being filled in by other tones. This feature makes the study of scales particularly important to understanding music and musical traditions.

Reliability

In order for a scale to be reliable, it must elicit consistent and stable responses from respondents. This is the definition of reliability, and it is very important to assess the reliability of a questionnaire before using it for predictive analysis. Variables derived from summated scales must also be reliable if they are to be used in objective models.

Coefficient alpha is a commonly used indicator of internal consistency, but it has serious limitations and can be misinterpreted. For example, it is often misused by mathematics education researchers who equate it with construct validity. This is similar to the indiscriminate use of coefficient alpha in other fields, such as psychology.

Fortunately, there are alternative methods for estimating reliability that do not suffer from these limitations. One such method is the split-half correlation. This method estimates the reliability of a measure by splitting the instrument into two halves and administering each half to different groups. The correlation between the two halves is then used to estimate the reliability of the entire instrument.

Dimensions

Using scales provides hands-on learning that encourages problem-solving. A balance scale is one of the most basic models that helps students understand how weights are weighed. It also teaches the concepts of size and quantity.

When working with scales, it is important to remember that the dimensions of a figure are multiplied by the scale factor to create larger or smaller versions of the original shape. It is easy for students to divide a number instead of multiplying it when dealing with scale factors, but this can lead to inaccurate answers.

This tab contains quite a few options that can be tweaked, but you can skip many of them for now. The Use overall scale of: field is crucial, as you learned in Chapter 6, and we recommend leaving it at its default value for now. Below it you will find the Center marks and Radius jog dimension categories, but these are mostly cosmetic settings and can be left alone for now.

Applications

Scale is an essential tool for businesses looking to increase production and customer outreach in a cost-efficient manner. By leveraging bulk purchasing, business scaling can reduce per-unit costs while expanding market reach increases revenue potential. Effectively implementing scale requires strategic planning to ensure that all aspects of the business are optimized for growth.

As businesses expand their reach into new demographic markets, they gain valuable insights and intelligence on the needs of their customers. This allows them to tailor products and services for a more niche audience, improving customer satisfaction and retention.

Scaling a software application means that it can handle more data or users without losing performance or functionality. This is achieved through scalable architecture, which uses different servers to distribute the load across all available resources. A scalable software application can also adapt to changing demands, which is important when handling sudden peaks in traffic or user activity. This type of scalability is often considered the mark of a high-quality application.

Measures are the observations collected by researchers and processed into the numbers that enable testing of pre-conceived hypotheses or derive new ones from exploratory analyses. This process may involve either designing a new measurement protocol or connecting existing validated scales to data.

In mathematics, a measure on a set has the properties of countable additivity and complete translation invariance. The Lebesgue measure is a special case of such a measure.

Scales of Measurement

The level of measurement or scale of a variable is one of the most important aspects to consider when performing statistical analysis. It determines the appropriate statistical techniques to use for the analysis of the data.

Scales of measurement vary in complexity and characteristics, ranging from simple and categorical (nominal) to more complex and quantitative (ratio). Understanding the different levels of measurement and their properties helps researchers properly analyze the data they collect.

Nominal scales are the crudest level of measurement and involve using numbers to label or categorize observations. They lack magnitude and have no true zero point. For example, when a researcher asks respondents to rate their favorite music styles, the ratings may be recorded on a nominal scale with names such as pop, rock, hip-hop, etc. Each of these categories represents a unique class or category of music but does not indicate any difference in type or quality. The interval scale combines the properties of the nominal and ordinal scales by having both identity and order and also by providing interval values with a meaningful relationship between them. The Fahrenheit and Celsius temperature scales are examples of an interval scale.

Ratio Scales

A ratio scale possesses all the characteristics of an interval scale, but also includes a true zero point. This makes it possible for data scientists to use a range of statistical techniques that cannot be applied to nominal, ordinal, or interval data. This includes descriptive and inferential statistics.

Ratio scales allow for a meaningful comparison between variables. This is because they have equal intervals and a real zero value. As such, they can be used to calculate meaningful multiplication and division. This is a crucial feature, which can be used in a number of ways, from calculating IQ scores to determining how much time a respondent spends playing video games. Moreover, they can be used to generate actionable feedback and conduct research. For example, respondents can be asked to rate their level of military experience on a ratio scale. They can then compare their results with other data points from the same survey. This will help to identify patterns and trends.

Quantitative Scales

Whether your data comes from a scientific experiment, or from your daily experiences, there are four primary levels of measurement scale type: nominal, ordinal, interval and ratio. Each has specific characteristics that define the type of data you collect.

Nominal (also known as categorical) scales assign numbers to observations that act as labels. They have no underlying relationship and don’t allow for any form of arithmetic computation (+, -, x, etc.).

The ordinal scale indicates order and rank, such as gender or ethnicity. Interval scales have all of the properties of an ordinal scale but allow for the calculation of differences between values using a true zero point. For example, the Celsius and Fahrenheit temperature scales use an interval scale. Lastly, the ratio scale has properties of both interval and ordinal, as well as allowing for calculation of mean, median and mode. It’s a great choice for data that requires an exact measure. Data from a student’s GPA would fit this category.

Qualitative Scales

Knowing the different types of data and scales of measurement can help you choose the right statistical tool for your survey. Nominal scales allow you to label observations as categories; ordinal scales define a sequence; interval scales measure the order of values and have a true zero point; and ratio scales combine characteristics of the previous two scales.

Nominal scales categorize observations into unique categories like male vs. female or a product’s features. This allows respondents to identify and evaluate the data.

Ordinal scales are similar to nominal in that they classify the data but also denote an order, for example male vs. female or educated vs. un-educated. Interval scales have properties of both the above, but they can also be used to rank data e.g. heaviest to lightest or ranks of players or students. The ratio scale combines the qualities of all these scales, except that it can be used to calculate central tendencies such as mean, median and mode.
