Number Base Converter
Convert a number between binary, decimal, hexadecimal, and octal bases instantly. Enter a value in any one base and the others update automatically — useful for low-level programming, color codes, and debugging.
Where each base is used
Binary (base 2) is how computers represent data at the lowest level.
Hexadecimal (base 16) is a compact way to write binary data — common
in color codes (#FF5733) and memory addresses. Octal
(base 8) shows up in Unix file permissions (e.g. chmod 755).
