ABSTRACT:
An electronic converter for converting numbers between two numeric systems, as for example, from the English to the metric systems. The converter comprises a dual keyboard for entering a number represented by a succession of digits and two calculators each having a display for displaying the contents stored in each calculator. The converter further comprises a direction control circuit which generates a signal identifying the actuated keyboard for each digit entered and a memory circuit programmed with a conversion algorithm for each direction of conversion between the two numeric systems. The appropriate conversion algorithm is selected by accessing memory in response to the actuated keyboard as identified by the direction control circuit. The selected memory information is controllably directed to one of the two calculators for performing the proper conversion. A conversion of the numerical information stored in the calculator occurs for each keyboard digit entered in the converter.
