About This Tool


Hexadecimal to decimal conversion translates base-16 numbers into our familiar base-10 decimal system. This is essential when working with hex values in programming, color codes, and system data.

Hex uses digits 0-9 plus letters A-F (representing 10-15). Each position represents a power of 16, making conversion similar to other base conversions.

For example, hex "FF" = 15×16¹ + 15×16⁰ = 240 + 15 = 255. This is why #FFFFFF (white) has RGB values of 255, 255, 255.

Our converter accepts hex in various formats: plain (FF), prefixed (0xFF), or with # (common in color codes). It handles both uppercase and lowercase letters identically.

This conversion is particularly useful for web developers working with color codes, programmers analyzing memory addresses, and anyone working with encoded hexadecimal data.

Frequently Asked Questions

What do A-F represent in hex?
A=10, B=11, C=12, D=13, E=14, F=15. These extend the single-digit concept beyond 9.
Why is hex used for colors?
Each color channel (R, G, B) uses one byte (0-255), which fits perfectly in two hex digits (00-FF).
What's the decimal for hex FF?
FF = 15×16 + 15 = 255, the maximum value for one byte.
Can I convert color codes?
Yes! Enter the hex portion of a color code (without #) to get its decimal components.
Is 0x required?
No, the 0x prefix is optional. Both "FF" and "0xFF" convert the same way.
