I meant cooking. You wrote that Fahrenheit has "marginal advantage" in cooking, I responded that unnecessary precision is a disadvantage if anything. As for body temperature the rule of thumb as I know it is sth like this: 36 - fine 36.6 - the theoretical perfect temperature (but it's a lie [1]) 37 - observe 38 - go see doctor (but no rush) 39 and higher - go see doctor immediately These also depend on where you measure the temperature, mostly people measure in armpits here, if you do oral or rectal then they will differ. Remote measuring on your forehead is almost useless. As for "requires medicine" - I don't remember having to make that decision, if I had 38+ C fever I just went to a doctor anyway. [1] the actual perfect temperature changes by almost 0.5 C between people, time of day, time of month (for women) and other factors (measurement error). If you used thermal method of anticonception you'll know how variable it really is.
