Abstract

PURPOSE:To perform efficient calculation including the conversion of a unit system by operating a selection key and converting the unit system on a conversion numeral on a unit display part selectively. CONSTITUTION:With a selection key 15 pushed, a unit indication part 16 provided to a display device 12 turns on and an A on a unit display part 14 is used as the unit in the metric system to perform the conversion of length, weight and capacity in the milli-system. With the key 15 pushed again, the unit indication part 16 turns off and a 17 turns on, so that units cm for length, gram for weight and liter for capacity are used for the metric system. When the key 15 is further pushed, a unit indication part 18 turns on and kilo is used as the units of the metric system. When the key 15 is surthermore pushed, the unit indication part 18 turns off and the unit display part 14 shows a fundamental unit system D.
