Fahrenheit to Rankine - How to Convert Fahrenheit to Rankine
The Fahrenheit (°F) scale is widely used in the United States for daily temperature measurement, while the Rankine (°R or R) scale is primarily used in engineering and thermodynamics.
Unlike Fahrenheit, Rankine is an absolute temperature scale, similar to Kelvin (K) but based on Fahrenheit increments. It starts at absolute zero (0 R), which is equivalent to -459.67°F.
To convert Fahrenheit to Rankine, use this simple formula:
Rankine (R) = Fahrenheit (°F) + 459.67
For example, to convert 212°F to Rankine:
212 + 459.67 = 671.67 R

Interesting Facts
-
Rankine and Kelvin are both absolute scales, but Rankine increases in Fahrenheit degrees, while Kelvin increases in Celsius degrees.
-
The Rankine scale was developed by William John Macquorn Rankine, a Scottish engineer and physicist, in 1859.
-
Absolute zero (0 R) is the lowest possible temperature, where all molecular motion theoretically stops.
-
The surface temperature of the sun is about 10,000 R (5,778 K or 9,940°F).
-
Rankine is widely used in thermodynamic calculations, especially in the fields of aerospace, mechanical, and nuclear engineering.
The Legacy of William Rankine
William John Macquorn Rankine was a Scottish physicist, engineer, and one of the founding figures of thermodynamics. His work contributed significantly to heat engines, energy conservation, and the study of thermodynamics.
Aside from inventing the Rankine scale, he also developed theories in steam engine efficiency and helped lay the groundwork for modern power generation systems. Today, Rankine cycles are fundamental to the design of steam turbines and thermal power plants.

Conclusion
Converting Fahrenheit to Rankine is incredibly simple—just add 459.67 to the Fahrenheit value. While Fahrenheit is used for everyday weather reports in the U.S., Rankine remains essential in thermodynamics, engineering, and power plant designs—leveraging reliable online conversion tools can streamline calculations and workflows.
