Rømer
The Rømer scale is a temperature scale that was proposed by the Danish astronomer Ole Rømer in 1701. While not directly related to angular measurement, it is a historical temperature scale where the freezing point of water is defined as 7.5 degrees, and the boiling point as 60 degrees. The scale was primarily used in Denmark and has since been largely replaced by the Celsius scale. Rømer's scale is of historical interest and highlights the early efforts to quantify temperature in a systematic way.
Réaumur
The Réaumur scale is a temperature scale developed by the French scientist René Antoine Ferchault de Réaumur. On this scale, the freezing point of water is 0 degrees, and the boiling point is 80 degrees under standard atmospheric pressure. While not as widely used as Celsius or Fahrenheit, the Réaumur scale was historically employed in some European countries for scientific and industrial purposes.
