    google search results only talk about changing it to decimal first, then afterwards to binary.

    how do i do a direct, manual conversion?

    It is much easier to convert between hex and binary than decimal and binary. Just write down the binary digits in groups of four. Each group then corresponds to a single hex digit (you can look them up in a table until you have memorised them). To do the conversion the other way, just write down the set of 4 binary digits corresponding to each hex digit.

    For octal, you just use groups of three binary digits instead. (Does anyone still use octal?)

    thats a 2 step way:
    1) oct to bin
    2) bin to hex

    but a 1step way (the question asked for the fastest way) is:
    1) oct to hex


    how do i do a 1step manual conversion?

    I suspect it is more complex than doing it in two steps, which is the simplest way I can think of...
