The measuring system that the United States uses right now isn't really a system at all. It's a hodgepodge of various units that often seem to have no logical relationship to one another, units collected throughout our history here and there, bit by bit. Twelve inches in a foot, three feet in a yard, 1,760 yards in a mile.
The metric system, by contrast, was intentionally created with ease and simplicity in mind. And as a result, it's incredibly efficient to use. All you need to do is multiply or divide by some factor of ten. 10 millimeters in a centimeter, 100 centimeters in a meter, 1,000 meters in a kilometer. Water freezes at 0°C and boils at 100°C.
Pretty convincing case, although I’m not really somebody who needed much convincing in the first place. But in a country home to a sizable population of folks who don’t believe in vaccinations or evolution, believe that airplanes are dusting us with mind control chemicals, and say that the jury is still out on a fact agreed upon by 97% of the experts studying it—I’m not going to hold my breath.
