A scale calibration method involves the use of a secure computer device with a GPS function to determine gravity strength at the location of installation of a scale (10). The scale (10) itself may include a self-calibration feature that enables the scale to automatically determine an appropriate gravity strength value for an operating location of the scale (10).
