What is wind chill?

The National Weather Service defines wind chill as follows:

The wind chill temperature is how cold people and animals feel when outside. Wind chill is based on the rate of heat loss from exposed skin caused by wind and cold. As the wind increases, it draws heat from the body, driving down skin temperature and eventually the internal body temperature.

The following chart from the National Weather Service matches wind speed with air temperature to give an approximation of what the temperature feels like.
