About This Conversion Table

This table lists all 256 values from 0x00 to 0xFF, showing their equivalents in decimal, binary, and octal. It's a quick reference commonly used by:

Programmers working with memory addresses, color codes, and byte values
Network engineers dealing with MAC addresses and IPv6
Students learning number systems and digital logic
Embedded systems developers working with registers and bitwise operations
Web developers converting between hex color codes and RGB values

Quick tips: Each hex digit represents exactly 4 bits (a nibble). The range 0x00-0xFF covers one byte (8 bits), which can represent 256 distinct values.
