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.

Rømer (°Rø): The Danish Astronomer's Temperature Scale

The Rømer scale, denoted as °Rø, was developed by Danish astronomer Ole Christensen Rømer in the early 18th century. It sets the freezing point of water at 7.5°Rø and the boiling point at 60°Rø. The Rømer scale played a crucial role in the development of later temperature scales, including the Fahrenheit scale, and is an important milestone in the history of temperature measurement.
