K = °Ré * 4 / 4 + 273.15

°Ré = ( K − 273.15 ) * 4 / 5


Scale information

Kelvin

The Kelvin scale is a thermodynamic (absolute) temperature scale referenced to absolute zero. The kelvin is a unit of measurement for temperature. Both are named after the Belfast-born engineer and physicist William Thomson, 1st Baron Kelvin (1824-1907), who in 1848 whote of the need for an "absolute thermometric scale". The freezing point of water is set at 273.15K and the boiling point at 373.1339K.

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.
