About Number Bases
Number bases (or radixes) define how many unique digits are used to represent numbers. Binary (base 2) uses 0-1, octal (base 8) uses 0-7, decimal (base 10) uses 0-9, and hexadecimal (base 16) uses 0-9 and A-F. This tool supports bases up to 36, which uses digits 0-9 and letters A-Z.
