Fahrenheit

The Fahrenheit (°F) temperature scale is used for measuring temperature in the US customary system of measurement. It is primarily used in the US and its territories. Most other countries use the Celsius scale.

The Fahrenheit scale is defined based on the freezing point and boiling point of water:

32 °F (the freezing point of water)

212 °F (the boiling point of water)

In the Celsius scale, the freezing point of water is 0 °C and the boiling point is 100 ° C.
