One way to assess your progress is to step on a body fat scale. Body fat scales are easy to use. You simply step on the scale, and the tool measures both your body weight and your estimated fat percentage. Such scales work with the help of sensors underneath your feet that use bioelectrical impedance. When you step on the scale, a small electrical current runs up through your leg and across your pelvis, measuring the amount of resistance from body fat. Then, the sensors in the scale measure the level of resistance that the current met as it travels back through your other leg.
Depending on the type of body fat scale you have, the information can link up to your smartphone or smartwatch, as well as any fitness apps you might have. As a rule of thumb, greater body resistance means a higher fat percentage. Shop online for body fat scales. In general, body fat scales can provide rough estimates only. While safe to use, there are many variables that can affect your results. These include:. The greatest benefit to using this type of scale is that you can measure your body fat in the comfort of your own home at any time, all without having to travel to a gym or clinic.
Body mass index BMI is perhaps a more reliable indicator of your overall health instead of counting on a body fat scale alone. So, an athlete with a lot of muscle, for example, could have a higher BMI based on their weight and height. Also, the CDC says that women, older adults, and people of Asian descent naturally have higher levels of body fat.
All of these factors can limit the reliability of BMI as your sole measurement of health. While stepping on a scale is perhaps the easiest method of body fat measurement, there are other ways you can determine your body fat percentage. Aside from BMI, you can ask your health provider about the following methods:. The National Heart, Lung and Blood Institute notes that your risk for heart disease and diabetes increases if you are a woman with a waist measurement greater than 35 inches Often used by fitness professionals, calipers are used to literally pinch your skin folds usually around the waist or hips to estimate your body fat.
The amount stored or the capacitance depends on the size of the gap between the plates. So, when an item is placed on the plate, the gap will decrease and create a change in the capacitance, which can then be calculated into weight. Marsden industrial scales can be used for weighing a wide variety of products and materials from fresh food ingredients to machinery parts, pallets and roll cages. The industrial scales we offer can be used in a range of work environments and include precision balances weighing to 1mg, to tonne crane weighers and professional axle weighers.
All of our scales work to the highest level of accuracy increasing productivity and quality control in the workplace. Whether you require a stainless steel scale for weighing produce, precision bench scales, counting scales or pallet track scales for fast despatch, we have a variety of sizes and prices to suit your industrial needs.
We also offer a range of advanced checkweighers, capable of documenting weights automatically and recording the data to a spreadsheet. While you're probably aware of scales being used in cooking and in industrial scenarios, we've compiled a list of weighing scale uses that may surprise you.
You may be wondering how accurate your weighing scales need to be. Read this blog post to find out. Have you ever had your scale serviced?
Find out why it's important here. How Do Weighing Scales Work? The Four Types of Load Cells Some differences between types of scales and how they work is due to the different types of load cells. Scales usually express accuracy as a percentage of full scale FS -- the total calibrated range a device can measure.
Alternatively, error can be expressed as percentage of actual reading AR : For an object weighing pounds on such a scale, a 2 percent AR would mean an error of 2 pounds, whether the scale had a range of 10 pounds or 10, [sources: AWS ; Busch; Plint].
The precision of a scale is similarly variable. By industrial standard, regardless of capacity, scales are split into a maximum of 10, divisions: Hence a 10,pound scale will divvy into one-pound increments, whereas a ,pound scale will divide into pound increments [sources: AWS ; Crowley ; Mashaney ]. Weighing devices are grouped into categories based on these divisions see sidebar. With this in mind, always try to select a scale that is has a high enough capacity to handle what you are measuring, but not much higher.
This will ensure you get the most precision possible, pound for pound. One of the joys of writing for HowStuffWorks. The deft engineering and intricately milled parts that go into these items are, alone, enough to inspire any technophile.
Look beyond the appurtenances and appliances to the heart of any device -- particularly one used for measurement -- and you find something even more wondrous: a physical law, ingeniously harnessed to an array of specific and useful tools. Nowhere is this truer than in scales. In this article alone, I encountered Hooke's law for springs; Pascal's law for fluid pressure; Boyle's Law , Charles' law and Gay-Lussac's law describing the behavior of gases; and Ohm's law for electrical resistance -- and that's to say nothing of the various unnamed laws governing stress and strain.
So the next time you encounter some politician who wants to cut science education in the name of balancing the budget, it might be worth reflecting that our most enduring fiscal facilitators, scales, are made possible by a centuries-old march of scientific discovery.

We Provide You're Gonna Carry That Weight Research, industry and commerce require the capacity to measure weights under a seemingly limitless variety of environmental conditions and space constraints, while also controlling for possible errors. All Scales Great and Small. Economies of Scale s " ". The digital scale that you trudge onto is the summation of some deft engineering and serious science. Show it a little respect, OK? Staying Within Your Weight Class.
Class I scales, commonly used in precision laboratory weighing, have a minimum of 50, divisions measuring 1 milligram or more each. Class III commercial scales weigh everything from postage to animals. They feature , divisions ranging from 0. Class IIIL devices consist of vehicle scales with 2,, divisions of 2 or more kilograms each. Read More. Sources American Weigh Scales, Inc. Personal correspondence. Cappella, B. Page 1.
