Most of the comments I have read on here are not in favor of the metric system due to your experiences. However , as a science teacher, I believe the metric system is much superior, and much , much, much easier to use. The metric system is based on 10's and the prefixes are universal. For example, milliliter, milligram, and millimeter are all 1/1000th of the base unit. Conversions are much simpler and there would be no such thing as fractions. Instead we use a system where the foot is based off one of the queen of England's foot length. We are America, we are arrogant.
Those against the metric system. How many inches in a foot ? inches in a yard ? feet in a yard ? inches in a mile ? feet in a mile ? yards in a mile ? teaspoons in a tablespoon, teaspoons in a quart, quarts in a gallon, pints in a gallon ? ounces in a pound ? Hopefully you get my point. There is no connection like in the metric system. Far superior system, we just aren't used to it. I'm for all metric except for football. 1st and ten baby, 1st and ten.
