Uhh, bad news for you guys. You don't realize it, but everything in the U.S. is based on metric standards. An inch is now *defined* as 2.54 centimeters. There is no separate standard for our idiotic system of measurements. Hell, 99% of U.S. citizens don't even know what our measure of mass is (slug). And, of the 1% who do know that, the vast majority of them probably couldn't calculate the mass of an object given its weight in pounds.
So, "only one superpower left and it doesn't use the metric system" is actually "the citizens in the U.S. don't even have a clue."
No one really cares how it's (currently) defined any more than metric system users care that their unit of length is defined as some wavelength of light.
And no one really cares what the unit of mass is, because we use units of mass and weight more or less interchangeably just like most of the rest of the world does; we use the unit of weight for both, and everyone else uses the unit of mass for both. As a European how much they weigh, and they'll tell you their mass. The people to whom mass and weight are not interchangeable use the metric system anyway, thus no one cares about the imperial unit of mass.
Actually, the unit of length is defined by how far light travels in a fraction during a certain amount of time. The speed of light is fixed by definition. (This made much more sense because as the precision of measurements improves, other standards don't have to be changed.)
Way to miss the forest for the trees. :roll:
