Contrary to what some believe, the wind chill factor does not lower the air temperature. It does not matter how strong the wind is; the temperature remains constant unless progressively colder air is moving into the region. The wind chill factor is a measure of how fast heat is being removed from your body. If the air temperature is 40 degrees and the wind is blowing at 20 miles per hour, it feels the same as 20 degrees with no wind at all.

Calculate the Wind Chill (Or consult the chart below) Input Temperature ° F : Input Wind (mph) : Wind Chill : ° F.

Cooling Power of Wind Expressed as "Equivalent Chill Temperature"
