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.

Delisle (°De): A Historical Temperature Scale

The Delisle scale, denoted as °De, was developed by French astronomer Joseph-Nicolas Delisle in the 18th century. This scale is unique in that it measures temperature in reverse; higher temperatures correspond to lower degree values. Although it has fallen out of common use, the Delisle scale remains a point of interest in the history of thermometry and the development of temperature measurement systems.
