Temperature - Ambient, Convert to and from Celsius and Fahrenheit

Formulae
°F = (°C * 9/5) + 32
°C = (°F -32)*(5/9)

Temperature - Engine Related, Convert to and from Celsius and Fahrenheit

Notes
100 degreesC = 212 degreesF = boiling point of water
0 degreesC = 32 degreesF = freezing point of water
-40 degreesC = -40 degreesF = point of agreement on both scales
