Rankine temperature conversion formulas
To find From Formula
Fahrenheit Rankine °F = °R − 459.67
Rankine Fahrenheit °R = °F + 459.67
Kelvin Rankine K = °R × 1.8
Rankine Kelvin °R = K ÷ 1.8
Celsius Rankine °C = (°R ÷ 1.8) – 273.15
Rankine Celsius °R = (°C + 273.15) × 1.8
For temperature intervals rather than specific temperatures,
1 °F = 1 °R
and
1 kelvin = 1.8 °R

The symbol is °R (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). As with the Kelvin scale (symbol: K), zero on the Rankine scale is absolute zero, but the Rankine degree is defined as equal to one degree Fahrenheit, rather than the one degree Celsius used by the Kelvin scale. A temperature of -459.67 °F is precisely equal to 0 °R. Rømer is a disused temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. ... The degree Réaumur is a unit of temperature named after René Antoine Ferchault de Réaumur, who first proposed it in 1731. ... For other uses, see Kelvin (disambiguation). ...

Many engineering fields in the U.S. measure thermodynamic temperature using the Rankine scale. However, throughout the scientific world where measurements are made in SI units, thermodynamic temperature is measured in Kelvin.

Rankine temperature scale, temperature scale having an absolute zero, below which temperatures do not exist, and using a degree of the same size as that used by the Fahrenheit temperature scale.
Absolute zero, or 0°R, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -459.67°F. Because the Rankine degree is the same size as the Fahrenheit degree, the freezing point of water (32°F) and the boiling point of water (212°F) correspond to 491.67°R and 671.67°R, respectively.
The temperature scale is named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.
Rankine - Wikipedia, the free encyclopedia (195 words)
Rankine is a thermodynamic temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.
The symbol is °R (note that this symbol is also used to stand for the Rømer and Réaumur scales).
As a result, a difference of 1 R° is equal to a difference of 1 F°, but 0 °R is −459.67 °F. The Rankine cycle is an idealised thermodynamic cycle for a steam engine, i.e.
