Binary / Hex / Decimal Table (0–255)

This binary, hexadecimal and decimal table lists the numbers 0 to 255 with their decimal, hexadecimal (base 16), octal (base 8) and 8-bit binary (base 2) representations. One byte holds values 0–255, which is exactly two hex digits (00–FF). Use it as a quick number-base conversion reference.

How number bases relate

Each hex digit equals exactly 4 binary bits, so a byte (8 bits) is two hex digits. For example decimal 255 = FF hex = 377 octal = 11111111 binary.
