Home > Rankine

Rankine is an thermodynamic (absolute) temperature scale in which zero is defined as absolute zero -273.15°C (the point where all spontaneous molecular motion ceases). The scale divisions are the same as those in Fahrenheit, 0°F = approximately 459.69.

It is named for the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

To figure out Rankine from the following scales, use the corresponding formula


Celsius
[°R] = ([°C] + 273.15) · 9/5
Delisle
[°R] = 671.67 − [°De] · 6/5
Fahrenheit
[°R] = [°F] + 459.67
Kelvin
[°R] = [K] · 9/5
Newton
[°R] = [°N] · 60/11 + 491.67
Réaumur
[°R] = ([°Ré] · 5/4 + 273.15) · 9/5
Rømer
[°R] = ([°Rø] − 7.5) · 24/7 + 491.67
