Why is Fahrenheit so weird?
It comes from Daniel Gabriel Fahrenheit, a German scientist born in Poland in 1686. As a young man, Fahrenheit became obsessed with thermometers. This may seem weird, but measuring temperature was a big problem at the time. Fahrenheit set zero at the lowest temperature he could get a water and salt mixture to reach.
