i assume most of it is a joke?

> It is more precise. Fahrenheit has more frequent degrees, allowing for greater resolution with analog thermometers.

this is really about the graduation and size of the thermometer? you can print a useful line pitch as you like, and have it represent what you want, where thats a 0.25C, 3F, 10c or whathaveyou.

everyday temperatures are pretty well centered around 0C, half the year above, the other half below, and the 10, 20, 30, and 40 increments feel quite similar to each other in severity of the season. +30 is damn hot and -30 is damn cold. +/-10 is all mildly warm or cold, with +/-20 really being where you do seasonal acitivites like swimming or skiing.

as far as western units go, C fits fantastically for the the traditional western culture with 4 idealized seasons. I could see F being better for places outside the idealized west - eg. the american south/sun belt, the PNW, southeast asia, south america, a lot of africa, etc where the seasons are different
