A method of calibrating a digital scale includes the steps of: () acquiring a first AD conversion value by the digital scale, the first AD conversion value corresponding to a weight of a reference object gathered before calibration; () acquiring a second AD conversion value by the digital scale, the second AD conversion value corresponding to a value when the digital scale has a weight reading of 0; () acquiring a target weight of a reference object; and () ascertaining a target AD conversion value per unit weight by reference to the first AD conversion value, the second AD conversion value and the target weight of the reference object, the target AD conversion value per unit weight being arranged to measure a weight of an object by the digital scale after calibration.
