Two measures are currently in use to describe the effects of wind on temperatures that are near or below freezing. The Wind chill factor is a measurement of the rate of heat-loss caused by the wind.
Watts are the same units that describe how much energy a light bulb requires per second.
Values for wind chill generally range from 1000 to 2500. The Wind chill equivalent temperature is a way of expressing the combined effects of temperature and windspeed in degrees Celsius. The wind chill is determined by the wind speed where you are. Our wind chill readings are based on the wind you would experience on open ground. There is no wind chill in this case.
