I agree, once you get used to hex there is little need for binary.

For those that don't know, here is a little tip for Binary to hex conversion:

Take a binary number (works for any number of bits, but lets choose 13 to demonstrate):

0b1101101101010

Split it into groups of four bits starting from right to left

1 1011 0110 1010

If there arent a multiple of four bits, then pad with zeros until there are (now you see why I chose 13)

0001 1011 0110 1010

Now convert each group into decimal [base 10] (you can skip this step when you get used to it)

1 11 6 10

Now convert each group into hex [base 16]

1 B 6 A

Finally, stick it back together, and you have your hexadecimal number:

0x1B6A
