BCD to Hexadecimal Converter
Convert Binary Coded Decimal (8421 BCD) to Hexadecimal (Base-16) Online - Accurate & Free.
What is BCD, Decimal, and Hexadecimal?
To fully leverage this converter, it’s beneficial to understand the number representations involved.
Binary Coded Decimal (BCD): BCD is a digital encoding method where each individual decimal digit (0 through 9) is represented by its own unique 4-bit binary sequence.
The most prevalent form, and the one our tool uses, is 8421 BCD. For example, the decimal number 256 is represented in BCD as 0010 (for ‘2’), 0101 (for ‘5’), and 0110 (for ‘6’).
A critical rule is that 4-bit binary patterns corresponding to decimal values 10 through 15 (e.g., 1010 to 1111) are invalid as individual BCD digits.
Decimal (Base-10): This is our standard number system, using digits 0-9. In the BCD to Hexadecimal conversion, decimal serves as the crucial intermediate form.
Hexadecimal (Base-16): Also known as “hex,” this system uses sixteen symbols: digits 0-9 and letters A-F (representing decimal values 10-15).
Hexadecimal is widely used in computing as a compact and human-readable way to represent binary data.Our BCD to Hex online tool manages these transformations efficiently and accurately.
How to Convert BCD to Hexadecimal: The Two-Step Method Explained
Converting a Binary Coded Decimal string to its hexadecimal representation is a precise two-step process, which our tool automates for you:
Step 1: BCD to Decimal Conversion
The input BCD string (typically composed of 4-bit groups, possibly space-separated) is processed.
Each 4-bit group is individually converted to its decimal digit equivalent. For example, BCD 0010 0101 0110 becomes:
0010 → 2
0101 → 5
0110 → 6
BCD Validation: It’s essential that each 4-bit group represents a decimal digit from 0 to 9. Any group representing a value from 10 to 15 (e.g., binary 1010) is an invalid BCD digit. Our tool flags such errors.
The valid decimal digits are then concatenated to form a complete decimal number (e.g., 256 from the example above).
Step 2: Decimal to Hexadecimal Conversion
The decimal number obtained from Step 1 is then converted to its hexadecimal (base-16) equivalent. For example, decimal 256 is converted to hexadecimal as follows:
256 ÷ 16 = 16 remainder 0
16 ÷ 16 = 1 remainder 0
1 ÷ 16 = 0 remainder 1
Reading remainders upwards (and converting remainders 10-15 to A-F if they occur) gives hexadecimal 100.
Our tool utilizes BigInt for this decimal-to-hexadecimal conversion to ensure accuracy even if the intermediate decimal number derived from a long BCD string is very large.
The output hex digits A-F are presented in uppercase.
This Binary Coded Decimal to Hexadecimal conversion logic ensures correct and reliable results.
How to Use Our Online UTF-8 to Binary Converter
Our tool is designed for simplicity and power. Here’s how to convert your UTF-8 text to its binary byte sequence:
1
Enter Your BCD String:
Locate the “Enter BCD String (8421 Code)” input field.
Type or paste your BCD string. You can use spaces to separate 4-bit groups for readability (e.g., 0010 0101 0110).
These spaces will be ignored during processing.
The input should consist only of ‘0’s and ‘1’s, and the total number of bits (after removing spaces) must be a multiple of 4.
Each 4-bit group must represent a decimal digit from 0 to 9.
Pro Tip: Click the “Import File” button to select a .txt file from your computer containing the BCD string.
Or, for quick input, use the convenient drag and drop feature to load your .txt file directly into the input area!
2
Click “Convert to Hexadecimal”:
Once your text is in the input field, simply click the vibrant amber “Convert to Hexadecimal” button.
View Your Hexadecimal Output:
The Hexadecimal Output field will instantly display the converted hexadecimal string, using uppercase letters A-F.
Error Handling: If your input BCD string is invalid (e.g., contains non-binary characters, length is not a multiple of 4, or any 4-bit group represents a value greater than 9), an error message will be clearly shown, guiding you to correct the input.
3
Copy or Download Hexadecimal Output:
Copy: Click the “Copy Hexadecimal” button to instantly copy the entire hexadecimal output to your clipboard.
Download: Need to save the output?
Choose your preferred format: TXT (plain text), CSV (the entire hexadecimal string in a single cell), or DOC (Word-compatible document).
Click the “Download” button.

Interactive Example: Your First BCD to Hexadecimal Conversion
Let’s try a quick example to see it in action.
In the input box, type: 0010 0101 0110
Now, click the “Convert to Hexadecimal” button.
You’ll see the output: [ 100 ]
Here, BCD to Decimal: 0010→2, 0101→5, 0110→6.
Resulting decimal: 256.
Decimal 256 to Hexadecimal: 100.
The final Hexadecimal output will be: 100

Frequently Asked Questions (FAQ)
-
Q1: What is a BCD to Hexadecimal Converter?
BCD (Binary Coded Decimal) to Hexadecimal Converter is a tool that translates numbers represented in BCD format into their equivalent in the hexadecimal (base-16) number system.
This is achieved by first converting the BCD to its decimal value, and then converting that decimal value to hexadecimal.
Our tool uses the 8421 BCD standard.
-
Q2: How does the BCD to Hexadecimal conversion work in this tool?
It’s a two-step process: 1. BCD to Decimal: Your input BCD string (sequences of 4-bit groups, each representing a decimal digit 0-9) is converted to its decimal equivalent.
For example, BCD 0001 0010 becomes decimal 12. 2. Decimal to Hexadecimal: This decimal number is then converted to hexadecimal.
For example, decimal 12 becomes hex C. So, BCD 0001 0010 converts to hex C.
-
Q3: What is 8421 BCD, and why is its validation important?
8421 BCD is the most common BCD scheme where each decimal digit (0-9) is represented by its unique 4-bit weighted binary pattern.
Validation is crucial because 4-bit binary patterns like 1010 (decimal 10) through 1111 (decimal 15) are not valid for representing a single BCD digit.
Our tool checks for this to ensure correct interpretation.
-
Q4: What happens if my BCD input contains an invalid 4-bit group, like 1010 (binary for 10)?
The tool will flag an error. Each 4-bit group in a valid BCD string must correspond to a decimal digit from 0 to 9.
If a group represents 10 or more, it’s an invalid BCD segment, and an error message will be displayed, indicating the problematic group.
-
Q5: Does the tool handle BCD strings with spaces?
Yes, you can input your BCD string with spaces between the 4-bit groups (e.g., 0001 0010); these will be ignored for processing.
-
Q6: Can this tool handle BCD strings that represent very large decimal numbers before converting to hex?
Yes. The intermediate conversion from the decoded BCD to decimal, and then from decimal to hexadecimal, uses BigInt arithmetic.
This allows for the accurate handling of BCD strings that would result in decimal and subsequently hexadecimal values.
-
Q7: How is the hexadecimal number formatted in the CSV export?
When you download the converted hexadecimal number as a CSV file, the entire hexadecimal string is placed within a single, properly quoted cell.
-
Q8: Is this online Binary Coded Decimal to Base 16 converter free?
Yes, our Online BCD to Hexadecimal Converter is completely free for all users and includes all its features.
Such as file import/export and rigorous BCD validation.
