How accurate is a normal weight scale?

According to a study, most home scales provide an accurate reading, within 0.9 kilogram of weight. Scales vary by type, with digital scales proving to be more accurate than dial scales.

The type of scale has a lot to do with the accuracy of the weight reading. Digital scales are more accurate than dial scales. If a person is weighing himself at home, he should weigh himself at the same time on the same day every week, wearing the same clothes each time and using the same scale on a hard, flat surface. These factors ensure a more accurate reading.
