The Wind Chill Calculator uses the following formulas to calculate the wind chill factor: WC (Wind Chill, °F) = 35.74 + 0.6215 × T - 35.75 × V 0.16 + 0.4275 × T × V 0.16. Excel Wind Chill Formula. where. How to calculate wind chill 35.74+.6215*T-35.75*W^.16+.4275*T*W&.16 Where T is temperature; W is wind speed For the most part, we can handle the cold. Enter a temperature, in either Fahrenheit or Celsius. They recruited a group of volunteers to walk on treadmills in a refrigerator blower. According to Wikipedia, "wind chill is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air. The wind chill calculator takes account of the wind speed in mph or km/h or m/s or knots and the actual air temperature in Fahrenheit or Celsius or Kelvin. Siple and Passel were measuring the effect of how wind blowing can cause an object to lose heat at a quicker rate. How do you calculate wind chill?
