naturekid88 saidYou understand that the international economy is based on the metric system, which is not taught in the United States?
"the international economy" ... "metric system" - You are making no sense. For the record, I know the metric system. I'm in the healthcare field. How exactly would kgs/mLs come into play when discussing economics?
Also, I don't know about you, but I learned the metric system in grade school and encountered it again in college.
By the way, what does this have to do with your OP or my response?
