Scale information

Celsius

The Celsius scale (also known as centigrade) is a temperature scale named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar scale. From 1744 until 1954 0°C was defined as the freezing point of water and 100°C as the boiling point (at standard atmospheric pressure).

Réaumur

The Réaumur scale (also known as "octogesimal division") is a temperature scale named after the French scientist René Antoine Ferchault de Réaumur (1683-1757), who first proposed something similar in 1730. The freezing point of water is set at 0°Ré and the boiling point at 80°Ré.
