"Wind chill" is actually, of course, a measurement of heat loss
through unprotected skin.  McCormick in "Human Factors" gives a
sensation scale in kilocalories per square meter per hour:
"hot"= 80, "pleasant"=200, "cool"=400, "cold"=800, "bitter cold"=1200.
He references Siple and Passel, Proc.Am.Phil.Soc v89p177 (1945).

I have read in another source (I forget where) that temperatures,
and wind chill equivalent temperatures, below -40 have little 
additional debilitating effect.  I cannot confirm this, however.
