I think of all the things I'd miss would be farenheit for day-to-day measurements. Of course it doesn't make much logical sense in the lab to use, but I know that in the sense of how the environmental temperature feels on me, 0 is frigidly cold, and 100 is blazingly hot. Where in celcius, 0 isn't that bad, and 100 is OH GOD MY SKIN IS MELTING OFFFFFFFFFFFFF.

I'd be fine with metrics in every other sense.
