centigrade is cool because the 0 point is something that makes sense, if it's negative degrees out you could see snow, you need to be super careful when driving, and if you have frost sensitive plants outside you need to take them inside. what happens at 0 degrees fahrenheit? nothing? what happens at 100 degrees? the outside temperature is the same as body temperature? ok good, cool and useful scale.

like everything else in burgerland it's completely based on nothing, impossible to convert to normal scale, and also it's only used by burgerites.
