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