The Number Base Converter transforms integers between binary (base 2), octal (base 8), decimal (base 10), hexadecimal (base 16), and any arbitrary base from 2 to 36. Positional notation conversion is a fundamental concept in computer science and digital electronics — hexadecimal is the native notation for memory addresses, color codes, and assembly language; binary is used in bitwise operations and hardware registers; octal represents Unix file permission modes. This tool converts instantly with no limit on input size.
