How This Works
Every number base represents the same quantity using a different number of digit symbols: binary uses 2 (0-1), octal uses 8 (0-7), decimal uses 10 (0-9), and hexadecimal uses 16 (0-9, A-F). This tool converts through decimal internally, then formats the result in your target base.
Examples
Decimal 10 = Binary 1010
Decimal 255 = Hex FF
Binary 1111 = Decimal 15
Hex A0 = Decimal 160
