Number Bases Conversion

Arbitrary number base conversion. On this page you can convert between bases 2 to 62 including base 64.

All bases from base 2 - base 36 are case insensitive e.g. A = a.
From base 37- base 64, 'numbers' are case sensitive, e.g. A != a. A = decimal 10, a = decimal 36.

The script is able to convert real numbers (not just integers) to other bases, although we stop at 10 decimal places (because such fractions tend to be infinitely long).

Enter the source number and other bases will be automactically calculated for you. Original script thanks to Paul Gregg.
