Wind Chill [2.0]

Updated by Travis Bates

IN THIS ARTICLE

Wind Chill is a measure of how cold it feels to the human body when the wind is factored in with the actual air temperature. It is based on the rate of heat loss from exposed skin caused by the combined effects of wind and cold. The wind chill temperature is always lower than the air temperature for values where wind chill is applicable. Wind speeds under 5 mph have a negligible effect on the wind chill. Wind speeds between 5 and 50 mph have the greatest effect. The change in wind chill at wind speeds above 50 mph is minimal.

There is an “Old” formula and a “New” formula for calculating wind chill. The new formula for wind chill was partially developed by using human subjects wired with heat temperature loss sensors as they walked in a cold wind tunnel. The formula used by ZENTRA is from the “New” wind chill calculation.

Wind chill (°C)  = 13.12 + 0.6215T – 11.37 (V^0.16) + 0.3965T (V^0.16) 

T = Temperature in degrees Celsius (°C) 

V = Wind velocity in kilometers per hour (km/h) 

Windchill is defined for temperatures below 10 °C (50 °F) and wind speeds above 4.8 km/h (3.0 mph).
