Wind Chill Equation

wind chill =

= 91.4 - ((91.4 - (temperature)) * (0.478 + (0.301* (SQRT((wind speed)))) - (0.02 * (wind speed))))

where:

• wind speed is in mph

• temperature is in °F

Limitations:

• wind speed must be >= 4 mph

• temperature must be < 92 °F

NOTE: The equation in the reference showed the latter half of the equation as  (0.478 + (0.301* (SQRT((wind speed) - (0.02 * (wind speed)))))). Since this did not give correct answers, adjustments were made to get the above equation.
