Each hex digit represents 4 binary bits (nibble):

0: 0000 (0)
F: 1111 (15)
1A: (1×16) + (10×1) = 26
FF: (15×16) + (15×1) = 255

About This Tool

What is Hexadecimal?

Hexadecimal (base-16) is a numeral system that uses 16 distinct symbols: 0-9 for values zero to nine, and A-F (or a-f) for values ten to fifteen. It's commonly used in computing and digital systems because each hex digit represents exactly 4 binary bits, making it a compact way to represent binary data.

Common Use Cases

Cryptography: Representing encrypted data, hashes, and keys
Programming: Memory addresses, color codes, and character encoding
Digital Forensics: Analyzing binary files and data structures
Network Security: MAC addresses, packet analysis, and protocol debugging
Web Development: Color codes (#FF0000), URL encoding (%20)
