switching the U.S. to the metric system.

Using the metric system will save money. For example, buying tool you won't have to buy the metric and the customary system. Also, it's less to remember. There aren't as many conversions to remember so it's easier to learn and remember. Then, it is more universal. Only 3 countries use the customary system, Burma, Liberia, U.S.. So switching it would be more universal.
