The wind chill factor (WCF) measures how cold it feels with a given air temperature, T and wind speed V. WCF has been implemented in Canada and the United States, resulting in a consistent index provided to help the public protect itself against the dangers of frostbite and hypothermia The formula for WCF is: WCF-35.7 +0.6T-35.7V0.16 +0.43TV016 where T is in Fahrenheit and V is in mph. Also WCF's threshold is T-50 F and V-3mph. The wind chill factor (WCF) measures how cold it feels with a given air temperature, T and wind speed V.
