Module:Convert base

This module allows any number base to be converted to any other number base up to base 15.

It provides 3 convenience functions: fromDec, fromHex, and fromBin, for converting from decimal, hexadecimal, and binary, to any other base; and one main function: fromBase, for everything else.

• {{Decimal to binary converter}}
• {{Decimal to hexadecimal converter}}
• {{Hexadecimal to decimal converter}}
