How do you know what the standard diameters are? With AWG, you know the "next size up" (number--) and the "next common size up" (next even number down) To double the diameter, you go down by about 6 AWG sizes. To halve the resistance you go down by about 3 AWG sizes. I really don't see much reason to ever change from the AWG system.
