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. Code:
