I do remember that @ski6jones. I came to the US as a grad student in the mid 80s and I had no idea that the metric system was not used over here. I remember watching the first Olympic games full of excitement for the long jump, high jump and then getting all frustrated when I saw the official boards displaying measures in meters and centimeters, but the announcers and the overlays were converting everything in feet and inches. What the heck are those???, I was thinking... oh, well. A few years later, I kind of know how to convert back and forth, but the fractions, the littles and little littles are still mind boggling!
