Formulas
°R = ( °Rø − 7.5 ) * 24 / 7 + 491.67
°Rø = ( °R - 491.67 ) * 7 / 24 + 7.5
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.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.Written by: Nicholas Tsakiris Alston
