About the Number Base Converter
Convert numbers between the bases used in computing and math. Input is accepted in any base from 2 to 36 (prefixes like 0x and 0b are understood) and converted exactly using big integers, so even 100-digit numbers stay precise.
How to use it
- Enter a number and choose its base.
- Read binary, octal, decimal and hex results.
- Optionally convert to any other base.
Good to know
- Only integers are supported, not fractions.
- Digits beyond 9 use letters a–z.
