Why do scales say I'm 40 pounds lighter than I really am?
How can I check if the scale is calibrated correctly?
One way to check is to use a calibration weight. You can purchase a calibration weight online or at a store that sells scales. Simply place the weight on the scale and see if it reads the correct weight. If it does not, that could indicate that the scale is in need of calibration or repair.
