Formulas
°R = °N * 60 / 11 + 491.67
°N = ( °R - 491.67 ) * 11 / 60
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.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.
