Full Answer

Fahrenheit is a thermodynamic temperature scale that gets its name from the German physicist Daniel Gabriel Fahrenheit. He was a pioneer in the manufacture of mercury thermometers who proposed the scale in 1724.

Two fixed temperature points define the Fahrenheit scale: the freezing point of water at 32 degrees Fahrenheit and the boiling point of water at 212 F at standard atmospheric pressure. On the scale, each degree is 1/180th of the interval that is measured between the boiling and freezing points of water. Notably, the scale defines a typical warm summer day in a temperate climate as 72 F and normal human body temperature as 98.6 F.

The Fahrenheit scale was used widely among English-speaking nations up until the 60s. During the mid to late 20th century, most countries in the world replaced the Fahrenheit scale with the Celsius scale, which also has its origin in the 18th century. Fahrenheit still appears as a supplementary scale in Canada and an informal scale in the United Kingdom.
