2. Scales: All You Need to Know about it

by Sudarsan

Scales are straightforward devices that can provide you with the most accurate measurements of weight. To find out more about scales, read on.

What are scales?

A scale is a simple device that can let you measure weight of a object very accurately. They come in many shapes and sizes, but they all work on the same principle – measuring weight by comparing it to an invariable standard.

There are three types of scales: balance beam scales, spring scales & digital scales. Balance beam scales are the oldest type of scale used for weighing things. Spring scales use mechanical force to measure weight, while digital ones use electrical signals to accomplish this goal.

What do one need to know about using a balance beam scale?

When using a balance beam scale, make sure that both objects being weighed are placed equally on either side of the fulcrum or pivot point on the scale’s beam. This is the bar that goes straight across the middle of the scale. You can also use a balance beam scale to determine mass by placing an object on one side and calibrating it to read zero before adding another thing to the other side.

What do one need to know about using a digital scale?

When using a digital scale, make sure that your objects are correctly placed on the weighing platform. The weight displayed will be affected by how you position your things on the platform – so try to get them as close together as possible. Also, if you’re looking for precision in your measurements, remember that most digital scales have a margin of error of +/- 0.05 grams.

How accurate are scales?

Scale accuracy depends on the type of scale you are using. Spring scales are generally less accurate than balance beam or digital scales, with an accuracy range of +/- 0.50 grams. Balance beam scales have an accuracy range of +/- 0.02 grams, while digital scales have +/- 0.05 grams.

What types of things can one weigh with a scale?

Scales can be used to measure the weight of both objects and substances. For example, you can use them to determine how much your luggage weighs before going on vacation or see how many ounces are in a pound by weighing food items at the grocery store. They can also be used for scientific purposes – like measuring the mass or density of different materials.

How do one clean scale?

There are a few simple steps you can take to keep your balance beam scales in good shape. First, try not to drop it or expose it to excessive force – this could cause the machine’s internal components to break and render it useless. Second, clean off any dust with a dry cloth before putting your scale away at night. Finally, make sure that there isn’t too much pressure on either side of its fulcrum or pivot point, as this will affect how accurately weight is measured.


Scales are a simple but essential tool for measuring weight. Whether you’re using a balance beam scale, digital scale, or spring scale, make sure to read the instructions carefully and calibrate it correctly before taking any measurements.
