What is BCD (Binary Coded Decimal)?
Binary Coded Decimal (BCD) is a digital representation method where each decimal digit is stored separately as a 4-bit binary number.
Unlike normal binary numbers, BCD keeps every decimal digit independent, making it easier for electronic systems to display and process decimal values.
Decimal number: 49 BCD conversion: 4 = 0100 9 = 1001 Result: 0100 1001
How to Convert BCD to Decimal
Follow these steps:
- Separate the BCD value into groups of 4 bits.
- Convert each 4-bit group into its decimal digit.
- Combine all decimal digits to get the final number.
BCD: 0010 0101 1001 Groups: 0010 = 2 0101 = 5 1001 = 9 Decimal: 259

Frequently Asked Questions
BCD conversion changes Binary Coded Decimal values into their normal decimal number format.
Each decimal digit in BCD is represented using 4 binary bits.
No. BCD stores each decimal digit separately, while binary converts the complete number into base-2 format.
Yes. Values from 1010 to 1111 are invalid in BCD because decimal digits only range from 0 to 9.
