What is a degree Fahrenheit (°F)?

A degree Fahrenheit (°F) is the unit of temperature used in the imperial system of measurement.


Who Invented the Fahrenheit Scale?

The Fahrenheit scale was created in 1724 by the German physicist Daniel Gabriel Fahrenheit. He based his scale on three fixed points:

  • The zero point (0 °F) was set by the temperature of a freezing mixture of brine (ice, water, and ammonium chloride).
  • The second point (32 °F) was the freezing point of water, and the third (96 °F) was his best estimate of the average human body temperature.
  • Later, the scale was tweaked so that the boiling point of water is exactly 212 °F—a full 180 degrees above freezing.

Where Is the Fahrenheit Scale Used Today?

While most of the world has adopted the Celsius scale for everyday temperature measurement, the Fahrenheit scale remains the official scale in the United States, its territories (like Puerto Rico and Guam), and a few other countries, including the Bahamas, Palau, and the Cayman Islands.

In the United Kingdom, both Fahrenheit and Celsius are used to describe temperature; Fahrenheit remains more familiar to older people and is often heard in casual conversation.


How to Convert Fahrenheit to Celsius (Formula)

You can easily convert any temperature from Fahrenheit to Celsius using a simple formula. To convert a temperature from Fahrenheit (F) to Celsius (C), subtract 32 from the Fahrenheit temperature and then multiply the result by 5/9.

The Fahrenheit to Celsius formula is: C = (F − 32) × 5/9

For example, to convert a pleasant day of 77 °F to Celsius: C = (77 − 32) × 5/9 = 45 × 5/9 = 25 °C
