Abstract
A microprocessor controlled microwave oven having a scale for providing a signal corresponding to the weight of a food body in the cavity to a microprocessor which calculates the microwave exposure time period as a nonlinear function of the weight. Generally, as the weight of the food body is increased, the time period of exposure per weight unit is decreased by a factor equal to the weight of the food divided by the weight of the food plus a constant where the constant may preferably be 0.1.
