Unit Explanations
Fahrenheit°F
Source UnitFahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure. This scale divides the interval between the freezing and boiling points of water into 180 equal parts. It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
Fun Fact
The Fahrenheit scale was the first widely used temperature scale.
Réaumur°Re
Target UnitThe Réaumur scale, denoted as °Re, is a temperature scale established by the French scientist René Antoine Ferchault de Réaumur in the early 18th century. The scale is defined such that 0 degrees Réaumur corresponds to the freezing point of water, while 80 degrees Réaumur corresponds to the boiling point of water at standard atmospheric pressure. The scale is a linear scale, meaning that equal intervals on the scale represent equal differences in temperature. This scale was particularly popular in Europe until the late 19th century but has since been largely replaced by the Celsius and Kelvin scales.
Current Use
Today, the Réaumur scale is rarely used but can still be found in some specific applications, particularly in historical texts and discussions about temperature measurement in the context of brewing and traditional practices. It is primarily of interest to historians and those studying the development of thermometry. The scale is sometimes referenced in educational contexts when discussing the evolution of temperature measurement.
Fun Fact
The Réaumur scale was once widely used in the brewing industry, particularly in France, for its relevance to fermentation temperatures.

Definition
Fahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure. This scale divides the interval between the freezing and boiling points of water into 180 equal parts. It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
History & Origin
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, a Polish-German physicist, in 1724. He based his scale on three reference points: the lowest temperature he could achieve with a mixture of ice, water, and ammonium chloride (0°F), the freezing point of water (32°F), and the average human body temperature (approximately 96°F at the time, now adjusted to 98.6°F).
Etymology: The term 'Fahrenheit' originates from Daniel Gabriel Fahrenheit's last name.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
💡 Fun Facts
- •The Fahrenheit scale was the first widely used temperature scale.
- •Fahrenheit initially set 0°F as the lowest temperature he could create in his lab.
- •Fahrenheit's original human body temperature scale was adjusted from 96°F to 98.6°F.

This scale was particularly popular in Europe until the late 19th century but has since been largely replaced by the Celsius and Kelvin scales.
History & Origin
The Réaumur scale was proposed by René Antoine Ferchault de Réaumur in 1730. It was initially developed for scientific use and was widely adopted in various fields, including brewing and meteorology. The scale's use in industrial settings, particularly in Europe, allowed for standardized temperature measurements that were crucial for various processes, particularly in the 18th and 19th centuries.
Etymology: The term 'Réaumur' derives from the name of its inventor, René Antoine Ferchault de Réaumur, a French naturalist who lived from 1683 to 1757.
Current Use
Today, the Réaumur scale is rarely used but can still be found in some specific applications, particularly in historical texts and discussions about temperature measurement in the context of brewing and traditional practices. It is primarily of interest to historians and those studying the development of thermometry. The scale is sometimes referenced in educational contexts when discussing the evolution of temperature measurement.
💡 Fun Facts
- •The Réaumur scale was once widely used in the brewing industry, particularly in France, for its relevance to fermentation temperatures.
- •René Antoine Ferchault de Réaumur also invented the alcohol thermometer, which used alcohol instead of mercury.
- •The scale is sometimes humorously referred to as the 'baker's scale' because bakers in France would often use it to monitor dough temperatures.
