A digital scale works best on a flat surface. When an object is placed on a digital scale, its weight causes its internal strain gauge to deform. The scale converts that amount of deformation to an electrical signal, runs the signal through a digital converter, and shows the weight on the scale’s display.
How does a weight scale work?
In simple terms, a balances measure mass, while scales measure weight. A scale displays weight by measuring a deflection; the springs are deformed by the load, and the force needed to deform the springs is measured, and converted into weight.
Are digital scales accurate?
In general, digital bathroom scales are more accurate than mechanical ones. When we’ve regularly calibrated our top and runner-up pick scales and used them on hard, flat surfaces at home, we’ve found that we also get acceptably accurate readings.

If you tend to move your device around the room, you will find yourself lamenting, “My digital scale keeps changing!” However, it’s common for them to give different readings when you weigh in different spots.

Why does my scale give me different numbers?
Initializing the scale resets the internal parts allowing the scale to find the correct “zero” weight and ensure accurate readings. If the scale is moved and you do NOT calibrate it, you are likely to see fluctuations in your weight. With one foot, press the platform of the scale so that numbers appear on the display.
What does 1 gram look like on a digital scale?
A 95% accurate digital scale would measure 1 gram equal to somewhere between 0.95 – 0.98 grams. A digital scale that measures mass in ounces will measure 1 gram as 0.0353 ounces.

Weigh two objects together. Place one object on the scale. Note the weight. Take it off and let the scale even back out. If it matches, the scale is accurate. If it doesn’t, try it again and see if it is off by the same number. If it is, it might be that your scale is always off by that amount.
