ABSTRACT:
A scale adapted for performing recipes in which the ingredients are given in customary volumetric measures such as cups, tablespoons and teaspoons. The user enters the name or code number of an ingredient which is displayed by the scale. The amount of the ingredient is displayed in volumetric terms or in terms of weight if desired. A processor in the scale accesses the volume-to-weight (V/W) ratio or weight-to-volume (W/V) ratio of the ingredient from nonvolatile memory and calculates the weight of the ingredient and stores it temporarily. The ingredient is added gradually to a mixing bowl on the scale after the tare weight of the bowl is cancelled. The processor continuously compares the stored weight with the increasing weight of the ingredient and notifies the user by means of the display when a comparison is read and, hence, when the desired volumetric amount of the ingredient has been entered. Other operating modes can also be selected.
