Fahrenheit to Rankine Converter (°F to °R)
Type a value in degrees Fahrenheit to see it in degrees Rankine instantly.
70 °F = 529.67 °R
Formula: °R = °F + 459.67
How to convert degrees Fahrenheit to degrees Rankine
Add 459.67.
°R = °F + 459.67
Example: 70 °F + 459.67 = 529.67 °R
Rankine relates to Fahrenheit the same way Kelvin relates to Celsius: identical degree size, but counted from absolute zero instead of an arbitrary zero point.

About the units
Degree Fahrenheit (°F)
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so one Fahrenheit degree is 5/9 of a Celsius degree. It is used for weather and cooking in the United States.
Degree Rankine (°R)
The Rankine scale is the absolute counterpart of Fahrenheit: it starts at absolute zero but uses Fahrenheit-sized degrees, so 0 °R = −459.67 °F. It still appears in US thermodynamics and engineering tables.
