Okay, the rest of the world can mock us for using the imperial system; 12 inches to a foot, 3 feet to a yard, 1760 yards to a mile seems pretty ridiculous. It's like converting knuts to a sickle. But what I will defend is Fahrenheit. If you're using Celsius for the weather, you're limited from about -15° to 40° because that's the only thing that's reasonable. If it's 100°, then we're all dead. Why would you want your measurement restricted to such a small amount? It's like when Harlan rented a BMW and to brag how fast it could go, the engineer had the speedometer reach up to 250mph. Except you're never going to drive that fast, so Harlan complained he was limited to about a quarter of the speedometer and it was hard to tell how fast we were actually going.

Celsius was meant for water, but Fahrenheit is for people. It's specifically created for the weather. There's no justifiable reason in this case for why Celsius is better than Fahrenheit; if you want to use something more scientific, why not just try Kelvins?
