There is a scientific basis to the wind chill factor. It is based on heat transfer rates. The average skin temperature is about 85 degrees. At 30 degrees, unprotected skin will lose heat at the rate of x btu/sq.ft/hr in still air. At 40 degrees and 10 MPH wind (wind chill of 28 degrees) the heat loss will be about the same. In general, a wind chill of x degrees means that the effects un unprotected humans are abut the same as x degrees in still air.
