Time to go metric

It seems that it is way past time to make the final plunge and finish the conversion to the metric system. We started many years ago and then abandoned the effort having managed to convert only soft-drink bottles to metric sizes. Yes, there are some conversion costs for some businesses; but the long-term benefits would more than make up for those costs. Our products would cost less to produce and market in the global economy if only one system was being used. Public education would soon have everyone comfortable with the new units (which are the ones used by our military establishment, for example).
