Convert Degrees Fahrenheit to Degrees Rankine (°F to °R)
°R = °F × 1 + 459.67. Convert degrees Fahrenheit to degrees Rankine with the exact formula, a common-values table and a free converter.
Conversion formula
°R = °F × 1 + 459.67
Temperature scales set their zero in different places, so this is an offset conversion, not a ratio. There is no single number you can multiply by: °F 0 is 459.67 °R, and doubling the input does not double the result. Apply the multiplier, then the offset, in that order.

Frequently asked questions
What is 1 °F in °R?
1 °F is 460.67 °R. Because temperature scales are offset rather than proportional, this figure is not a multiplier: 100 °F is 559.67 °R, not 100 times 460.67.
What is the formula to convert degrees Fahrenheit to degrees Rankine?
°R = °F × 1 + 459.67. Apply the multiplier first, then the offset. Every value in the table on this page is computed with that formula by the same converter the tool below runs.
How do I convert degrees Rankine back to degrees Fahrenheit?
Use the inverse formula, °F = °R × 1 - 459.67. The °R to °F page carries the same table in that direction.
