What is BCD (Binary-Coded Decimal)?

Binary-Coded Decimal (BCD) is a binary representation of decimal digits, where each digit from 0 to 9 is encoded using its 4-bit binary equivalent. For example:

Decimal: 59
BCD: 0101 1001

Each digit is treated individually, making BCD especially useful in systems where decimal accuracy and simplicity in display operations are crucial, such as:

  • Digital clocks
  • Electronic meters
  • Programmable logic controllers

What is a Hexadecimal Number?

A hexadecimal (base-16) number uses 16 digits: 0–9 and A–F. It offers a compact way to represent large binary or decimal numbers and is frequently used in:

  • Memory addresses in computer systems
  • Digital electronics
  • Web development (e.g., color codes)
Decimal: 255 → Hex: FF

How to Convert BCD to Hex Manually

Step-by-Step:

  1. Split the BCD into 4-bit groups.
  2. Convert each group into its decimal digit.
  3. Combine the digits to form a full decimal number.
  4. Convert the decimal number to hexadecimal.

Example:

BCD Input: 0001 0010 0011
Step 1: Split → 0001 (1), 0010 (2), 0011 (3)
Step 2: Decimal → 123
Step 3: Hex → 7B

Understanding the BCD to Hex Conversion Process

BCD uses only 4-bit combinations from 0000 to 1001 (decimal 0–9). Any 4-bit sequence beyond 1001 (e.g., 1010, 1111) is not a valid BCD digit.

Why convert to Hex?

  • Compact representation: BCD 0001 0000 = Decimal 10 → Hex A
  • Efficient memory use in programming
  • Simplified display for programmers and systems engineers

Applications of BCD to Hex Conversion

BCD to Hex conversion is widely used in:

  • Embedded systems (microcontrollers, Arduino, etc.)
  • Assembly programming
  • Digital circuits and electronic timers
  • BCD-based I/O devices

Frequently Asked Questions

Q1. What is the valid range of digits in a BCD number?

Each 4-bit group must represent digits between 0000 (0) and 1001 (9). Values beyond this are invalid in standard BCD encoding.

Q2. Why does my BCD input return an error?

This usually means you’ve entered a binary pattern outside the BCD range. Double-check that each nibble (4-bit group) represents a digit 0–9.

Q3. What is packed vs unpacked BCD?

  • Packed BCD: Stores two digits per byte.
  • Unpacked BCD: Stores one digit per byte.

This tool supports both formats when properly grouped.
