The wind chill factor can not lower a temperature below the current air temperature, but instead it speeds up the decrease in temperature proportional the speed of the wind Both the Old model for calculating the Wind Chill Factor, pre-2001 formula, and the New Wind Chill Index devised by the National Weather Service in 2001 are used. The values are calculated to the second decimal place for extra accuracy. Inputs for Air Temperature can be given as Fahrenheit or Celsius. Acceptable inputs for wind velocity are Knots, Miles per Hour, and Kilometers per Hour.
