About this calculator

This converter decodes binary-coded decimal (BCD), an encoding where each individual decimal digit (0–9) is stored in its own 4-bit binary group rather than converting the whole number to pure binary — for example, decimal 47 is stored as two nibbles, 0100 (4) and 0111 (7), not as the pure-binary 101111.

BCD trades some storage efficiency (since 4 bits can represent up to 15 but only 0–9 are used) for the ability to convert to and from decimal instantly, digit by digit, with no rounding or conversion error — which is exactly why it's long been favored in digital clocks, calculators, seven-segment displays and financial/accounting hardware where exact decimal representation matters.
