2.Should the U.S. Switch to Metric System?

My answer would be yes. Several years ago NASA rocket failed cause of the mistake on the measurements. The first reason that I think the U.S. should be using metric system, is that it makes everything so much easier to understand. The metric system changes the unit, but doesn't change the number only the unit of the number by adding a 0 or subtracting 0. Example:14554cm equals to 145540mm. Another reason why i think U.S. should be using the metric system is cause its international, any country can use it easily for communications on information and data.
