What makes it superior? A meter, a yard = the distance from ypor nose to your out streached finger. Weight makes no sense a gram or kilogram is a mass weight is force so here the SAE system makes more sense. Like I said before having the two systems gives an oportunity to teach kids about numbers. Think about fractions for a second 12 devides by 2,3,4,6 with whole number results and rational fractions with 8,9, & 10. What othe base does that. 16 is nice because 16/2/2/2 = 2. Not all that dumb for a base either. Like I said fun with numbers.
