Abstract
A selectable program unit is stored within a combined electronic digital scale and calculator. The selectable program unit includes three programs to obtain the area of a triangle or a circle, and the volume of a rectangular solid. Selection keys for selecting one of the stored programs are provided on the body of the combined electronic digital scale and calculator. The programs are used in conjunction with measurement results determined by an extensible tape member housed within the combined electronic digital scale and calculator. Adjusting the extensible tape member to an object to be measured obtains the measurement results regarding the object. The selective program unit may include unit conversion programs for converting the unit of centimeter to that of the Japanese foot, the inch, and the foot. The combined electronic digital scale and calculator has also conventional calculation functions responsive to actuated number and function keys formed on the body thereof.
