Should Americans (re)adopt the metric system? The US was supposed to go metric back in the early to mid 70s, but the effort just seemed to fizzle and die. The increased accuracy in measurements, reduction of errors in production facilities and improved scientific thinking of those in the education system would seem to make this conversion inevitable, but the cost would be enormous. Everything from street signs and road maps would all have to be converted (some are already). Less obvious are the impacts on the manufacturing sector. The producers of machine tools, equipment and parts would face massive retooling costs in many cases. Sadly, going metric is much like a decision as to what side of the road you will drive upon. You can't do a partial adoption or gradual changeover to such a comprehensive policy. Swift conversion to metric would represent an astronomical cost, which seems to be the ultimate disincentive for America to do so. Peace.
