Abstract
An electronic postal scale measures the weight of an item in metric or in avoirdupois units, at the user's election. The scale also calculates a postal or shipping rate for the item, in accordance with a stored rate table defined in either metric or avoirdupois units. When the user selects a class of service, the scale determines whether there is a stored rate table for that class in the currently elected weight units. If not, the scale automatically changes to the other weight units and calculates a rate according to a stored table in those other units.
