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).
Fahrenheit
The Fahrenheit scale is a temperature scale named after the German physicist Daniel Gabriel Fahrenheit (1686-1736), who proposed it in 1724. The freezing point of water is set at 32°F and the boiling point at 212°F (at standrd atmospheric pressure).
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.
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.
Newton
The Newton scale is a temperature scale named after the English physicist, mathematician (and more) Isaac Newton (1642-1726), who devised it around 1700. He defined "zeroth degrees of heat" as melting snow and "33 degrees of heat" as boiling water.
Delisle
The Delisle scale in a temperature scale named after the French astronomer Joseph-Nicolas Delisle (1688-1768), who invented it in 1732. The freezing point of water is set at 150°D and the boiling point at 0°D.
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.
Rømer
The Rømer scale is a temperature scale named after the Danish astronomer Ole Christensen Rømer (1644-1710), who proposed it in 1701. The freezing point of water is set at 7.5°Rø and the boiling point at 60°Rø.
