Description

Réaumur (°Ré): The 18th Century French Temperature Scale

The Réaumur scale, symbolized as °Ré, was introduced by French scientist René Antoine Ferchault de Réaumur in the early 18th century. It sets the freezing point of water at 0°Ré and the boiling point at 80°Ré. This scale was widely used in Europe, particularly in France and Germany, for several decades. While it has been largely replaced by the Celsius scale, the Réaumur scale remains a significant part of the history of thermometry.

Rankine (°R): The Absolute Fahrenheit Scale

The Rankine scale, symbolized as °R, is an absolute temperature scale used mainly in engineering fields, particularly in the United States. It combines the Fahrenheit degree with the concept of absolute zero, starting at 0°R. The Rankine scale is essential in thermodynamic calculations where temperature differences are measured in Fahrenheit degrees, such as in aerospace and mechanical engineering applications.
