About number bases

A number base (or radix) determines how many unique digits are used to represent values - binary (base 2) uses only 0 and 1; decimal (base 10), the one you use every day, uses 0-9; hexadecimal (base 16) adds the letters A-F for values 10-15. This tool supports every base from 2 to 60: digits 0-9, then A-Z for values 10-35, then a-z for values 36-59. Above base 36, uppercase and lowercase letters are different digits (e.g. in base 40, “A” and “a” are not the same value) - for base 36 and below, case does not matter.
