Wind Chill is a mysterious and often misunderstood phenomenon. Wind Chill is a measure of the cooling effect of wind. Wind increases the rate at which a body loses heat, so the air on a windy day feels cooler than the temperature indicated by a thermometer. This heat loss can be calculated for various combinations of wind speed and air temperature and then converted to a wind chill equivalent temperature (or wind chill factor). Enter wind speed in mph and air temperature in Fahrenheit.
Fahrenheit (symbol °F) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named.
