Who's the smart-ass who decided that our units of measurement should stay different from that of the rest of the world? Why use units that seem completely arbitrary? For example, who decided that a foot is 12 inches and that a mile is 5280 of those feet? Aren't those numbers a little arbitrary? Who decided to measure weight in pounds, which is made up of 16 ounces, and that 2000 pounds shall be called 1 ton? Again, the numbers seem arbitrary.

As humans, we've learned to count in base 10. We have 10 fingers. We're usually best at counting and representing numbers in powers of 10s. The metric system uses multiples of 10 to work. A kilogram is 1000 grames. Kilo means 1000, 1000 is a power of 10, so there you go. They didn't pick some arbitrary number like 16275 or something stupid like that.

Our tempetature scale is retarded too. 32° is freezing and 212° is boiling? Don't be a smart-ass. Just use 0° and 100°. And whoever thought up Kelvin as a temperature scale was a real smart-ass too. "It's like Celcius, but you add 273°! And when you have 0° Kelvin, it's Absolute Zero." Don't be a smart-ass. That'd be like me inventing a temperature unit called Krak. It's like Farenheit, but you subtract 212. When it reaches 0, the temperature is boiling. That'd make me a real smart-ass.

So my question is: if the rest of the world uses the metric system, and it ultimately makes more sense for us to measure things in terms of 10s, then why do you continue to use our stupid system of inches, miles, pounds, ounces, tons, etc.?
