How to convert degrees Fahrenheit to degrees Rankine
°R = °F + 459.67
Example: 25 °F → 484.67 °R
Temperature scales have different zero points, so you cannot convert them with a single multiplication factor.

About these units
Fahrenheit (°F): Fahrenheit (°F) puts water’s freezing point at 32° and boiling point at 212°. It is used for everyday temperatures in the United States.
Rankine (°R): The Rankine scale (°R) starts at absolute zero like kelvin but uses Fahrenheit-sized degrees. It appears in some US engineering work.
