What is a Rankine degree?
A Rankine degree (ΔR or °R) as a temperature difference is exactly the same size as a Fahrenheit degree, 5/9 of a kelvin. A change of 18 °R is a change of 18 °F or 10 K. The Rankine scale itself starts at absolute zero, so it is used where US engineers need an absolute scale in Fahrenheit-sized steps.
Where the Rankine degree sits among temperature difference units
The Rankine degree is number 3 of 9 on our scale of temperature difference units, ordered from smallest to largest.
What Rankine degrees are used for
- US thermodynamics and gas-turbine engineering.
- Ideal-gas calculations in US customary units.
Rankine degrees in real life
- A 9 °R rise equals a 9 °F or 5 K rise.
