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.
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.
