1 degree Fahrenheit is equal to 1 degree Rankine.
The reason for this is because Rankine scale is directly offset from Fahrenheit, where both scales have the same incremental size. Since Rankine starts at absolute zero, 0° R equals -459.67°F, but when converting temperatures above absolute zero, the values are equivalent numerically.
What is the conversion from Fahrenheit to Rankine?
The conversion from Fahrenheit (°F) to Rankine (°R) is straightforward: since both scales share the same degree size, you simply add 459.67 to the Fahrenheit temperature. This converts the temperature to an absolute scale starting at absolute zero, which is 0° R.

Conversion Formula
The formula to convert Fahrenheit to Rankine adds 459.67 to the Fahrenheit temperature. It’s because Rankine is based on the Fahrenheit degree but starts at absolute zero, which is -459.67°F. So, the conversion formula is R = F + 459.67.
- Suppose Fahrenheit temperature is 100°F.
- Apply the formula: R = 100 + 459.67.
- Calculate: R = 559.67° R.
- This means 100°F equals 559.67° R.
Conversion Example
- Convert 10°F:
- Start with 10°F.
- Add 459.67 to it.
- Result is 10 + 459.67 = 469.67° R.
- Convert -20°F:
- Start with -20°F.
- Add 459.67.
- Result is -20 + 459.67 = 439.67° R.
- Convert 32°F:
- Start with 32°F.
- Add 459.67.
- Result is 32 + 459.67 = 491.67° R.
- Convert 0°F:
- Start with 0°F.
- Add 459.67.
- Result is 0 + 459.67 = 459.67° R.

Conversion Definitions
Fahrenheit
The Fahrenheit scale measures temperature based on human body temperature and freezing/boiling points of water, with zero at a point set by historical standards, where 32°F is freezing, and 212°F is boiling at standard pressure.
Rankine
Rankine is an absolute temperature scale using the Fahrenheit degree, starting at absolute zero (-459.67°F). It measures thermodynamic temperature, where 0° R is absolute zero, and degrees increase the same as Fahrenheit degrees.
Conversion FAQs
What is the significance of adding 459.67 in Fahrenheit to Rankine conversion?
Adding 459.67 adjusts the Fahrenheit temperature to account for absolute zero, aligning it with the Rankine scale which begins at absolute zero. This ensures the scale measures all temperatures above absolute zero accurately.
Can I convert Rankine to Fahrenheit directly?
Yes, but by reversing the formula. To convert from Rankine back to Fahrenheit, subtract 459.67 from the Rankine temperature. Because both scales share the same degree size, this reverse operation gives the Fahrenheit equivalent.
Why is Rankine scale important in thermodynamics?
Rankine provides an absolute temperature measure for engineering calculations involving heat and energy, similar to Kelvin but based on Fahrenheit degrees. It simplifies thermodynamic equations by starting at absolute zero.
