Rømer (°Rø)

Definition

Rømer (°Rø) is a temperature scale where 0°Rø was set to the freezing point of brine, 7.5°Rø to the freezing point of water, and 60°Rø to the boiling point of water.

History

The Rømer scale was created in 1701 by Ole Christensen Rømer, a Danish astronomer. Fahrenheit visited Rømer and was inspired by his work, later developing his own scale based on similar reference points.

Current use

The Rømer scale is no longer used practically. It is notable in the history of thermometry as the scale that inspired Fahrenheit's work, and appears in academic discussions of temperature measurement history.

Réaumur (°Ré)

Definition

Réaumur (°Ré) is a temperature scale where 0°Ré equals the freezing point of water and 80°Ré equals the boiling point of water.

History

The Réaumur scale was proposed in 1730 by René Antoine Ferchault de Réaumur, a French scientist. It was widely used across Europe, particularly in France, Germany, and Russia, until the late 19th century.

Current use

The Réaumur scale is nearly obsolete but still occasionally referenced in European cheese-making and some Italian candy-making traditions. It also appears in historical scientific texts.
