Scale information

Rankine

The Rankine scale is a thermodynamic (absolute) scale named after the Scottish engineer and physicist William John Macquom Rankine (1820-1872), who proposed it in 1859. The freezing point of water is set at 491.67°R and the boiling point at 671.64102°R.

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.
