WIND CHILL
Wind increases the rate at which a body loses heat. The air on a windy day feels colder than that indicated by a thermometer. Calculations of wind speed and air temperature indicate the WIND CHILL equivalent temperature.

FAHRENHEIT: Developed in the early 1700's by G. Daniel Fahrenheit, degrees Fahrenheit are used to record surface temperature measurements by meteorologists in the United States. However, most of the rest of the world uses degrees CELSIUS (developed in the 18th Century).

CELSIUS is also known as CENTIGRADE. Temperature is expressed in degrees Celsius in the Metric System. The boiling point of water (at sea level) is 100░Celsius, or 100░C. The freezing point of water (at sea level) is 0░ Celsius.

KELVIN is another unit of temperature that is very handy for many scientific calculations. It begins at absolute zero and therefore has no negative numbers.
NOTE: the word "degrees" is NOT used with Kelvin.
