1/6 of half a rotation = 1/12 of a rotation = 1/12 of 360 degrees = 360/12 = 30 degrees.
pi/12 = (pi/12)/(2pi) = 1/24 of a circle ( = 15 degrees).
Roof pitch is measured in "rise over run". In other words, how many inches does the roof rise vertically in 12" of horizontal run. If a roof rises 4" in 12" of run, you have a 4/12 roof pitch.
12 degrees Celsius = 53.6 degrees Fahrenheit.
