About the Hex to BCD Converter
The Hex to BCD Converter transforms hexadecimal (base-16) numbers into their Binary-Coded Decimal (BCD) equivalents. Hexadecimal numbers, commonly used in computing and digital electronics, are converted here into BCD — a format where each decimal digit is represented by its own 4-bit binary sequence.
This conversion is useful in systems where numerical data needs to be displayed or processed in a decimal-friendly format, such as seven-segment displays and BCD counters. The tool converts your hex value to decimal first, then encodes each decimal digit individually — giving you an accurate BCD result instantly, without manual calculation.
How to Use This Tool
Enter a hexadecimal number
Type or paste the hex value you want to convert, e.g. "2A".
Click "Convert to BCD"
The hex value is converted to decimal, then each digit is encoded as 4-bit BCD.
Copy the BCD output
Use the "Copy BCD" button to save the result.
Common Use Cases
Debugging Embedded Systems: Convert hex register or memory values into BCD form to check against decimal displays.
Teaching Number System Conversions: Demonstrate the hex-to-decimal-to-BCD conversion chain for a digital electronics course.
Interfacing with BCD-Based Displays: Convert hex values into the BCD format expected by seven-segment displays and BCD counters.
Verifying Manual Calculations: Double-check a manual hex-to-BCD conversion done by hand for a homework or lab assignment.
Why Use This Tool
Accurate Conversion
Converts hex to decimal first, then encodes each decimal digit as 4-bit BCD.
Handles Any Length
Works with hex values of any length, from a single digit to large numbers.
Great for Learning
A clear, instant way to see how hexadecimal, decimal, and BCD relate to each other.
