Number Base Conversion

Convert numbers between different bases.

Usage

Choose the base of your number and enter it in the input field. The number is shown in binary, octal, decimal and hexadecimal at once, each with a button to copy it.

The arrow button next to a result uses it as the new input, e.g. to continue from the hexadecimal value.

Numbers can be of any size and may be negative. Spaces and underscores used to group digits are ignored, as are the prefixes 0b, 0o and 0x.
