I'll actually defend Fahrenheit more strongly than other US units. 32 degrees is a single number it's probably worth remembering. Balanced against that, environmental temperatures are usually going to be positive unless it's really fricking cold and the degrees are about twice as granular. The main advantage of Celsius is just that it's what's used in most places (and that it's tied in with metric units).

The absolute scale of Celsius (as opposed to the size of the degree) isn't the most useful anyway because you tend to use Kelvin for a lot of purposes.
