The following wind-chill tables show the equivalent wind-chill temperatures in degrees Fahrenheit and degrees Celsius according to the temperature across the top and the wind speed along the side.

Wind Chill (F) = 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)

Note: V is the wind speed value in mph Note: T is the temperature in F Note: Frostbite occurs in 15 minutes or less at wind chill values of -18 or lower.
