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.
Celsius
Celsius is a unit of temperature measurement that is part of the metric system. It is named after the Swedish astronomer Anders Celsius, who developed the scale. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees under standard atmospheric pressure. It is widely used in scientific and everyday contexts around the world.
