I learned both systems in school--our rulers always had inches and centimeters--but we never really learned the metric system until much later in science classes. I think there's a strong argument to be made that the metric system is easier to learn and could be taught at the same time as counting and basic arithmetic. It would make learning science and math easier in higher grades and waste less class time. I'm honestly surprised there are so many comments here defending the Imperial system.
