Converting 1 Fahrenheit to Rankine gives a result of 1 Rankine. Since Fahrenheit and Rankine scales are closely related, this conversion confirms that 1 degree Fahrenheit equals 1 degree Rankine.
The Rankine scale starts at absolute zero and increases the same way as Fahrenheit, meaning that to convert Fahrenheit to Rankine, you just add 459.67. Therefore, 1°F is 1 + 459.67 = 460.67 Rankine, but for 1°F, the correct is 1 + 459.67 = 460.67 Rankine.
Fahrenheit to Rankine Conversion
The conversion from Fahrenheit to Rankine is simply adding 459.67 to the Fahrenheit temperature. This works because Rankine scale begins at absolute zero (0 R) and Fahrenheit scale begins at the freezing point of water (32°F), with the size of each degree being the same in both scales. So, to convert, you add the offset of 459.67 to the Fahrenheit value.

Conversion Formula
The formula to convert Fahrenheit to Rankine is: R = F + 459.67, where R is Rankine and F is Fahrenheit. This formula works because Rankine starts at absolute zero, which is 459.67 degrees below freezing point of water in Fahrenheit. Adding this offset aligns the scales.
For example, if you have 10°F, then in Rankine it will be 10 + 459.67 = 469.67 R, which positions the temperatures correctly in absolute terms.
Conversion Example
- Convert 20°F to Rankine:
- Start with 20°F.
- Add 459.67 to 20.
- 20 + 459.67 = 479.67 R.
- Result: 20°F equals 479.67 Rankine.
- Convert -10°F to Rankine:
- Start with -10°F.
- Add 459.67 to -10.
- -10 + 459.67 = 449.67 R.
- Result: -10°F equals 449.67 Rankine.
- Convert 0°F to Rankine:
- Start with 0°F.
- Add 459.67 to 0.
- 0 + 459.67 = 459.67 R.
- Result: 0°F equals 459.67 Rankine.
- Convert 100°F to Rankine:
- Start with 100°F.
- Add 459.67 to 100.
- 100 + 459.67 = 559.67 R.
- Result: 100°F equals 559.67 Rankine.

Conversion Definitions
Fahrenheit
The Fahrenheit scale measures temperature with 32°F as freezing point of water and 212°F as boiling point, based on a scale developed by Daniel Gabriel Fahrenheit. It is primarily used in the United States for everyday temperature readings.
Rankine
The Rankine scale is an absolute temperature scale starting at absolute zero, with equal degree intervals to Fahrenheit. It is mainly used in thermodynamics and engineering in the United States, with 0 R at absolute zero and freezing point of water at 491.67 R.
Conversion FAQs
Why do I need to add 459.67 to Fahrenheit to get Rankine?
This addition aligns Fahrenheit with absolute zero, which in Rankine is 0 R. Since Fahrenheit starts at 32°F for water’s freezing point, adding 459.67 shifts the scale to start at absolute zero, making conversions straightforward and consistent.
Can I convert Fahrenheit to Rankine for any temperature?
Yes, the formula applies to all Fahrenheit temperatures because Rankine is an absolute scale. Whether the temperature is below freezing or above, you just add 459.67, ensuring accurate conversion regardless of the value.
Is Rankine used outside the United States?
Rankine is primarily used within the United States for scientific and engineering purposes. Outside the U.S., Celsius and Kelvin are more common, but Rankine remains relevant for specific thermodynamic calculations where Fahrenheit units are preferred.
What is the significance of absolute zero in Rankine?
Absolute zero, at 0 R, marks the lowest limit of temperature where particles have minimal thermal motion. The Rankine scale’s zero point is directly linked to this, making it suitable for thermodynamic calculations in imperial units.
How does converting Fahrenheit to Rankine help in thermodynamics?
Converting Fahrenheit to Rankine allows scientists and engineers to work with absolute temperature values in imperial units, which is essential for calculations involving heat, energy, and thermodynamic cycles where absolute scales are necessary.
