I see you mentioned earlier that you're from GB. It's great that you've taken interest in the metric system, but this is certainly a subject where you're wrong. I learned to use cm for person height in school, as did everyone else in Europe (except for GB) and Japan. cm is used in every country that uses metric units.  
 ::::::Once again. How did you decide on meters for person height? I would still like to hear the answer. Now don't take this personally; I have nothing against you. It's just that I really think it would be better if you wrote it correctly from the beginning and other people wouldn't have to correct you.
