metric system

I think that United States shouldn't change the metric system because it's not necessary to change it like other countries. It is not difficult to learn how to measure things in another way in fact I think that it is actually easier using this ones in United States than in the other countries all tho people in another country might think the opposite because they are use to doing it their way, and that is another reason why we shouldn't change it because people here in United States are use to doing it our way and it would be a little difficult changing it.
