Very true.

If you wish to manually convert the numbers, look at them from a base 16
perspective.  I.e., each digit represents a power of 16.  So for a 2 digit hex
number, like a4, do the following:

#a4 = a * 16^1 + 4 * 16^0 = 10 * 16 + 4 * 1 = 164 decimal

hex numbers are 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f

It's a bit tricky going the other direction (dec to hex), but fairly straight
forward with only three decimal digits.  To convert from dec to any other base,
use the remainder method.  E.g., to go from 200 dec to hex, do the following:

200/16 = 12 remainder 8
12/16 = 0 remainder 12, and 12 in hex is c
therefore, 200 dec = c8 hex

Hope this helps.
