About the Fahrenheit scale

Fahrenheit is a relative temperature scale created by the Polish-German physicist Daniel Gabriel Fahrenheit. It is mainly used in the United States and is less common in science compared to the Celsius (or Centigrade) scale.

Fahrenheit is based on the freezing and boiling points of water at standard atmospheric pressure with 32°F at freezing point and 212°F at boiling point.

Whilst Fahrenheit is still commonly used in the United States it is important to note that most of the world relies on Celsius.

About Celsius

Celsius is the most commonly used temperature scale in the world. The Celsius scale (known as the centigrade in some instances) is named after the Swedish astronomer Anders Celsius. It is based on the freezing and boiling points of water at standard atmospheric pressure making 0°C the freezing point and 100°C the boiling point.

The Celsius scale is normally found in weather forecasts, household temperatures and cooking in most countries with the notable exception of the United States.
