Temperature (°F) Wind Speed (mph) Wind Chill (°F) Old Formula

New formula

Wind chill temperature = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

In the formula, V is in the wind speed in statute miles per hour, and T is the temperature in degrees Fahrenheit.

Old formula

Wind Chill temperature = 0.0817(3.71V0.5 + 5.81 - 0.25V)(T - 91.4) + 91.4
