Bcd To Binary Converter
Enter the bcd value to convert to binary or Binary to BCD.
BCD:
BCD (Binary-Coded Decimal) represents each decimal digit as a separate 4-bit binary group.
Binary:
Binary (Base-2) is the standard binary representation of the full number.
How to Convert BCD to Binary — Formula:
For each 4-bit BCD group: digit = parseInt(group, 2). Combine digits to decimal, then decimal.toString(2).
Example: BCD 0010 0010 → digits 2, 2 → Decimal 22 → Binary 10110.
Technical Details:
BCD wastes some bit patterns (1010-1111 are invalid per digit) but simplifies decimal display. Packed BCD stores 2 digits per byte. Unpacked BCD uses 1 byte per digit.
Bcd To Binary Converter:
Convert BCD to binary by decoding each 4-bit group to a decimal digit, then converting the full decimal to binary.
