Decimal to BCD Converter
Convert decimal numbers into Binary Coded Decimal (BCD) instantly. This Decimal to BCD Converter converts each decimal digit into its 4-bit binary representation for electronics, programming, and digital logic applications.
Decimal to BCD Conversion Examples
| Decimal | BCD |
|---|---|
| 5 | 0101 |
| 9 | 1001 |
| 12 | 0001 0010 |
| 25 | 0010 0101 |
| 59 | 0101 1001 |
How Decimal to BCD Conversion Works
Binary Coded Decimal (BCD) represents each decimal digit separately using a 4-bit binary value. Unlike normal binary conversion, BCD does not convert the complete number into one binary value.
Example: Convert decimal 59 into BCD.
| Decimal Digit | 4-bit BCD |
|---|---|
| 5 | 0101 |
| 9 | 1001 |
Therefore, decimal 59 in BCD format is 0101 1001.
BCD vs Binary Representation
| Decimal Number | Binary | BCD |
|---|---|---|
| 25 | 11001 | 0010 0101 |
| 59 | 111011 | 0101 1001 |
| 99 | 1100011 | 1001 1001 |
Binary represents the entire number as one value, while BCD stores each decimal digit separately.
Common Uses of BCD Conversion
- Digital clocks and electronic displays.
- Calculators and measurement devices.
- Embedded systems and microcontrollers.
- Financial and commercial systems requiring exact decimal representation.
Frequently Asked Questions
A Decimal to BCD Converter changes each decimal digit into its 4-bit Binary Coded Decimal representation.
Decimal 59 is represented as 0101 1001 in BCD. The digit 5 becomes 0101 and the digit 9 becomes 1001.
Binary converts the complete decimal number into base-2 format, while BCD converts each individual decimal digit into a separate 4-bit binary code.
BCD is useful when exact decimal digits need to be displayed or processed, especially in clocks, calculators, and electronic measurement systems.
Standard BCD is designed for decimal digits only. Character encoding systems like ASCII are used for letters and symbols.
