Number Base Guide
Number bases (also called radices) determine how many unique digits are used to represent numbers. Common systems include binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). Base 36 uses all digits 0-9 and letters A-Z.
Converting between bases is fundamental in computing, cryptography, and mathematics. Our tool supports all bases from 2 to 36 with arbitrary precision using BigInt.
