How Hexadecimal Works
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. It's widely used in computing because it's more compact than binary and aligns perfectly with byte boundaries.
Hex Digits
A=10, B=11, C=12, D=13, E=14, F=15
Why Hex is Useful
- One hex digit = 4 binary bits (nibble)
- Two hex digits = 8 binary bits (byte)
- More compact than binary (FF vs 11111111)
- Easy to convert to/from binary
- Standard for colors, memory addresses, and data

Frequently Asked Questions
What is hexadecimal?▼
Hexadecimal is a base-16 number system using digits 0-9 and letters A-F (representing values 10-15). It's commonly used in computing because each hex digit represents exactly 4 binary bits, making it a compact way to represent binary data.
Why do programmers use hex?▼
Hex is more human-readable than binary while still aligning with computer architecture. One byte (8 bits) can be represented by exactly 2 hex digits. This makes hex ideal for memory addresses, color codes, and viewing raw data.
What does 0x mean before hex numbers?▼
The "0x" prefix is a convention in programming to indicate that the following number is hexadecimal. For example, 0xFF means 255 in decimal. This tool supports input with or without the 0x prefix.
How do hex colors work?▼
Hex colors use 6 digits representing RGB values. #FF0000 means Red=FF (255), Green=00 (0), Blue=00 (0), which is pure red. Each color channel uses 2 hex digits (00-FF or 0-255 in decimal).
Can I convert emojis to hex?▼
This tool uses ASCII encoding for simple text-to-hex conversion. Emojis require Unicode (UTF-8) encoding with multiple bytes. While you can encode them, the hex output will be the UTF-8 byte sequence, not a simple 2-digit code.
What's the difference between hex and binary?▼
Both represent the same data differently. Binary uses base-2 (0-1), hex uses base-16 (0-F). One hex digit equals 4 binary digits. "FF" in hex equals "11111111" in binary, both representing 255 in decimal.
