A number base converter converts between binary, octal, decimal, and hexadecimal number systems.
Convert numbers between binary, octal, decimal, and hexadecimal in real time as you type.
A number base converter translates numbers between different positional numeral systems: binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). Each system uses a different set of digits — binary uses 0-1, octal uses 0-7, decimal uses 0-9, and hexadecimal uses 0-9 plus A-F. For example, the decimal number 255 equals 11111111 in binary, 377 in octal, and FF in hexadecimal.
Base 2 (0-1) | Base 8 (0-7) | Base 10 (0-9) | Base 16 (0-9, A-F)
