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.

Delisle

The Delisle scale, proposed by the French astronomer Joseph-Nicolas Delisle, is a temperature scale where the freezing point of water is 150 degrees and the boiling point is 0 degrees under standard atmospheric pressure. The Delisle scale is unique in that its values decrease as temperature increases, making it less common in contemporary usage compared to other temperature scales.
