The metric system is the tool of the devil! My car gets 40 rods to the hogshead, and that's the way I likes it! — Grandpa Abe Simpson on the metric system
If you have friends who live in other countries, you might occasionally hear them ask, more or less rhetorically, why the hell we Yanks are still stuck with the English system of weights and measures. After all, Mother England herself went metric (and even decimalized the pound sterling) more than five decades ago. As of now, only two countries other than the United States use the English system: Liberia and Myanmar. Neither of them is exactly on the global cutting edge of science and technology, which suggests that maybe the U.S. has a problem.
