I think Fahrenheit is actually better for common use. People easily understand that temperatures near 0F are cold enough to hurt or kill you if you don't take precautions, and temperatures near 100F are hot enough to hurt or kill you if you don't take precautions; they correspond to about -18C to +38C, which are awfully strange numbers to try and remember.

I can see a reason to move distance and volume measures to metric, but not common temperatures.
