So I was wondering... when every other measurement in the world is divided between Imperial and Metric systems of measurement, why time is measured the same for everyone? Non-standard measuring systems even differ country to country. I'm pretty sure no other country measures anything in length of a "football field", which we know as Americans is 100 yards. Britain is pretty much the only place that measures in terms of a "stone", which is actually an Imperial metric of 14 pounds. So why then is time in hours, minutes, and seconds for everyone? Anyone know?
