Rankine is a
temperature scale that, like
kelvin, sets zero at
absolute zero, but uses
Fahrenheit degrees. A difference of 1 degree R. is equal to a difference of 1 degree F, but
absolute zero is 0 degrees R, or -459.67 degrees F. Thus:
- To convert from Fahrenheit to Rankine, add 459.67.
- To convert from Rankine to Fahrenheit, subtract 459.67.
- To convert from kelvin to Rankine, multiply by 1.8.
- To convert from Rankine to kelvin, divide by 1.8.
