Hexadecimal Basics

Base-16 number system using digits 0-9 and letters A-F (or a-f).

  • 0-9: Represent values 0-9
  • A-F: Represent values 10-15
  • Example: 0xFF = 255 decimal

Common Uses

  • Color codes (e.g., #FF0000 for red)
  • Memory addresses
  • Binary data representation
  • Cryptographic hashes
  • MAC addresses
  • Character encoding

Hex to Decimal

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

Tips & Tricks

  • Two hex digits = 1 byte
  • Prefix with 0x in programming
  • Case insensitive (0xff = 0xFF)
  • Leading zeros don't change value
  • Use spaces for readability

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)
