I was wondering if there is a easy way to go between all the different bases. From Hex to Octal and binary? This is where I can get confused. Any Quick tricks? Binary to Decimal is easy and vice-versa. Just the others seems confusing.
Thanks
Faisal

Hi Faisal,
1) Hex to Binary
Convert every digit into 4 bit Binary.
e.g) A6 = 1010 0110
2) Binary to Hex
Group by 4 bits from right to left, then convert each group to Hex equivalent.
e.g) 101011 = 0010 1011 = 2B
3) Oct to Bin and Bin to Oct would have the procedure as above, but with group of 3 bits instead of 4 bits.
4) For Oct to Hex and Hex to Oct, there need to be an intermediate binary conversion. i.e, Oct to Bin to Hex and Hex to Bin to Oct.
Hope that helps.
B Arul.
