WindChill

summary

Wind chill calculator

instructions

Put in the temperature and wind speed in y and x
respectively. Can take either (Farenheit, Miles/Hour) or (Celsius,
Kilometers/Hour).

It uses the Siple formula used by the US National Weather Service (see
http://www.srh.noaa.gov/ffc/html/wci.htm).

Note that the formula is only approximate (there is no exact formula) and
that it is only good at low temperatures.
