Fahrenheit (°F)

The degree Fahrenheit (symbol: °F) is a unit of temperature proposed in 1724 by physicist Daniel Gabriel Fahrenheit. On this scale, the freezing point of water is defined as 32 °F and the boiling point at standard atmospheric pressure is 212 °F, creating an interval of 180 degrees. One degree Fahrenheit is equal to 5/9 of a kelvin. The scale remains widely used for everyday weather, domestic heating, and cooking primarily in the United States and its territories.
