# Thread: Is there a way to do a direct conversion from hexadecimal to binary?

3. 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?)

4. 7. Convert octal 3057 to hexadecimal in the quickest way possible. Show your working.
my question....

5. You now know how to convert octal to binary and binary to hex therefore the answer is ....

6. 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...
