Wind Chill Calculator

Apart from calculating wind chill, this is also useful for simply converting temperatures and speeds between different units. For a brief description of wind chill factors check out this page. This calculator uses the Court formula which was developed in 1945. 

Baseline conditions are:

91.4°F and 4 mph (33°C and 1.8 m/s) i.e. don't bother putting in temperatures above 33°C or wind speed lower than 4mph because it won't return a meaningful result.
