We spend more time trying to learn the metric system when we are older than is necessary. If we had been using the metric system already, we might not have to take so much time to teach it to older students, and we might spend more time on science education.
Yes, the metric system is not hard if we learned it as young children. Having America on the metric system would make it much easier for us to be on the same terms as the rest of the world, which uses this system. One of these days we will have it. Might as well start teaching our kids now.
Yes, it would be easier for the United States to be on the same terms as the rest of the world if we had the metric system.
