TO DETERMINE THE WINDCHILL,
find the outside air temperature on the top line, then read down the column to the measured wind speed (MPH - Miles Per Hour.)
FOR EXAMPLE,
When the outside air temperature is 0 degrees F and the wind speed is 20 MPH, the rate of heat loss is equivalent to -22 degrees F without wind.
This chart replaces older versions prior to 2001.
It is based on the following formula -
Wind Chill (oF) = 35.74 + 0.621T - 35.75(V0.16) + 0.4275T(V 0.16)
T = Air Temperature (oF)
V = Wind Speed (mph)
V = Wind Speed (mph)
