Hex and Binary Reference

Hex-to-binary conversion is very intuitive: each hex digit maps exactly to 4 binary digits. Learn the table below to do it mentally:

Hex	Binary	Description
0	0000	Hex 0 maps to binary 0000
1	0001	Hex 1 maps to binary 0001
2	0010	Hex 2 maps to binary 0010
3	0011	Hex 3 maps to binary 0011
4	0100	Hex 4 maps to binary 0100
5	0101	Hex 5 maps to binary 0101

Typical Uses of Hex

Hex is the compact form of binary; each hex digit stands for exactly 4 binary digits, greatly shortening long numbers. It is the most common notation when reading memory addresses, color values and binary files.

When inspecting MAC addresses, memory dumps or debugging low-level data, hex makes long binary strings far easier to read and write, an indispensable aid in development and operations.
