The temperature scale is named after the German physicist Daniel Gabriel Fahrenheit (1686 – 1736), who proposed it in 1724.
In Fahrenheit scale, the freezing point of water is 32 degrees F (written: "32 °F"), and the boiling point is 212 degrees, placing the boiling and freezing points of water exactly 180 ° apart. On the Celsius scale, the freezing and boiling points of water are precisly 100 degrees apart, thus the unit of Fahrenheit scale, is 5/9 of a degree Celsius. Negative 40 degrees Fahrenheit (-40 °F) is equal to negative 40 degrees Celsius (-40 °C).
