How to use Hex to Decimal Converter
- Type the numberType or paste it into the box for its base. The other boxes fill in as you type.
- Read the bitsThe bits are drawn below with their places; small numbers are written as a sum of powers of two.
- Pick a width if it mattersFor negative numbers or register values, choose 8, 16, 32 or 64 bits to see two's complement and the signed value.
Paste a hexadecimal value, from code, a memory dump or a colour, with or without 0x or #, and read it in decimal and binary at once. Values of any length convert exactly, so 64-bit addresses and long identifiers work. Choose a width to see the value as a signed number too.
