FAQ
What is the formula to convert degrees Fahrenheit to degrees Rankine?
°R = °F + 459.67. For example, 37 °F = 496.67 °R.
How do I convert degrees Rankine back to degrees Fahrenheit?
°F = °R − 459.67; the degrees Rankine-to-degrees Fahrenheit page applies it directly.
Why is there no single multiplication factor?
Temperature scales have different zero points, so the conversion is an affine formula (scale and offset), not a plain multiplication.
