Frequently Asked Questions
Binary (base 2) uses only the digits 0 and 1. It's the fundamental language of computers, since electrical circuits have two states: on (1) and off (0). The decimal number 10 in binary is 1010.
Hexadecimal (base 16) uses digits 0–9 plus A–F (representing 10–15). It's widely used in programming to represent colours (like #FF5733), memory addresses, and binary data more compactly — one hex digit = 4 binary bits.
This converter supports bases 2 through 36. Base 36 uses all 10 digits (0–9) plus all 26 letters (A–Z), making it the practical maximum for standard alphanumeric characters.
