Decimal to BCD Converter

What is the Decimal to BCD Converter?

The Decimal to BCD Converter is an online utility designed to translate standard decimal numbers (base-10) into Binary Coded Decimal (BCD) sequences. BCD is an encoding system where each individual digit of a decimal number is converted separately into its own 4-bit binary representation. BCD is highly popular in digital displays, calculators, and automation controllers where decimal output must be directly mapped onto physical screens.

How to Convert Decimal to BCD

Converting a decimal value to BCD is incredibly straightforward. Since BCD is a digit-by-digit mapping, you simply take each digit of the decimal number and convert it directly into its 4-bit binary block:

• 0 → 0000
• 1 → 0001
• 2 → 0010
• 3 → 0011
• 4 → 0100
• 5 → 0101
• 6 → 0110
• 7 → 0111
• 8 → 1000
• 9 → 1001

Example: Convert decimal 925 to BCD:
- Convert 9 → 1001.
- Convert 2 → 0010.
- Convert 5 → 0101.
- **BCD Output**: 1001 0010 0101.

Key Features of Our Converter

• Infinite Precision: Because this BCD converter processes decimal values on a character digit basis, it has 100% infinite precision. You can convert decimal integers of any length (even millions of digits) instantly.
• Batch Line Conversion: Convert single numbers or massive lists of decimal integers at once, separating BCD outputs nicely by lines.
• Block Separators: Customize the separator between the 4-bit BCD groups, supporting spaces, dots, dashes, or plain text without gaps.
