The handy thing about the metric scale is that 0 is the freezing point.
Considering that it takes so much more heat to change a state than to
heat or coll something one degree, it marks a significant point. Below 0
is freezing, above 0 is not. I think that most people are better able to
distinguish a difference of one degree C than one degree F.

After a while you get used to the numerics that denote your comfort
zones, or discomfort, as the case may be.
