Some scales are so accurate they can measure amounts as small as a tenth of a gram. If your scale does, use the pennies to check the accuracy because they weigh 2.5 grams each. Turn on the machine and make sure it is at zero. If the weight it still off, your scale is likely inaccurate.
Correspondingly, can digital weighing scales be wrong?
Over time, scales can lose accuracy due to plain old wear and tear due to regular use and age. Electronic scales may suffer malfunction in the circuitry over time that can cause loss of accuracy. Even new scales may become inaccurate in certain conditions especially in extreme temperatures.
Secondly, why does my scale change weight? #1 Every time a digital scale is moved it needs to be calibrated.

How do you calibrate a scale without weights?
The calibration has to be done with nothing on the scale. First, turn the power on, then press the “Zero” or “Tare” button if there is one present.

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.
