Hexadecimal to Octal

[thamizhinpan]

What is the shortcut methord to convert hexadecimal numbers to octal numbers

[da_silvy]

You convert each of the hex digits to binary, four binary digits to a hex digit

e.g. 4F (79) 4 = 0100, F = 1111
so 4F in binary is 01001111

To convert to octal, you group the binary digits in groups of 3, e.g.
001|001|111
Then you convert this binary pieces back to decimal:
1|1|7

So 79 in hex is 4F in octal is 117

Hope that helps
