Raffaele,
ff translates into 255. Probably the easiest way to compare hex values is to use the calculator which is supplied with NT or Win2000, it has a "scientific" option which allows you to transfer numbers between decimal, octal and hexadecimal formats.
Other than that you would need to look into the counting scheme for hex numbers, they range from 1-9 and then A, B, C, D, F. F would correspond to decimal 15. FF would correspond to 15*16^1 + 15*16^0 = 255
