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.
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.
