°Ré = ( K − 273.15 ) * 4 / 5

K = °Ré * 4 / 4 + 273.15


Scale information

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.

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.
