    Frequently asked questions

    How do you convert binary to hex?

    Split the bits into groups of four from the right, padding the leftmost group with zeros, then replace each group with its hex digit. 110110101 → 0001 1011 0101 → 1B5.

    Why does 4 bits make one hex digit?

    Four bits can represent 2⁴ = 16 values (0000 to 1111), exactly the 16 hex digits 0-F. That is why hex is used as shorthand for binary.

    What is 11111111 in hex?

    11111111 is FF: two groups of 1111, each F.

    Do I need to pad with zeros?

    No. The converter pads automatically. Leading zeros do not change the value.

    Can I convert long bit strings?

    Yes. Any length works, and spaces or underscores between groups are ignored.

    What about the signed mode?

    In two's complement mode the bit pattern is kept as is and padded to the chosen width, so the hex shows the same bits. The decimal card shows the signed value.
