Diver0001:Third, the US headcount is only something around 20% of the world population, which means if there were 10 people in a room, only two of them would be American and of those two one probably won't care and one would be a world "thought leader" that already used the metric system in his/her work. I hardly think that the rest of the world be inclined to give much thought to who was "right" and nobody *at all* would be inclined to follow the apathetic one....
Actually, it's under 5% or one in twenty. There are over 6 billion people in the world and only 300 million in the U.S.
If I recall correctly, the U.S. is officially metric but it's not in common usage. Probably Britain is similar with its miles, stones, and pounds. In fact, I seem to recall that my American cars from the 80's used metric bolts, not "English."
