What is the wind chill formula?
WIND CHILL FORMULA(S): If you have units of wind in mph and temp in degrees F… try this: T(wc) = 0.0817(3.71V**0.5 + 5.81 -0.25V)(T – 91.4) + 91.4 T(wc) is the wind chill, V is in the wind speed in statute miles per hour and T is the temperature in degrees Fahrenheit.
