I would just like to go on record here and declare that I think that, for day-to-day living, the Fahrenheit temperature scale is superior to the Celsius scale.
Normal range of temperatures experienced by human beings on earth: 0 to 100 Fahrenheit. That's minus 17 to plus 37 Celsius -- not only is it completely ridiculous to have zero right in the middle of the range, but it's only half the number of degrees! So in order to get the kind of precision that Fahrenheit provides (for day-to-day living), you have to talk about fractions of degrees Celsius. Um, no thanks.
