Samantha Nicole0 degrees Fahrenheit is equal to 459.67 degrees Rankine.
The Rankine scale starts at absolute zero, similar to the Kelvin scale, but uses Fahrenheit-sized increments. To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit value, because Rankine zero is absolute zero, which is -459.67 °F on the Fahrenheit scale.

Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
This works because the Rankine scale sets zero at absolute zero, which corresponds to -459.67 °F. Since both Fahrenheit and Rankine use the same size increments, converting only requires shifting the zero point by adding 459.67.
For example, converting 0 °F:
- Start with 0 °F
- Add 459.67 to 0
- 0 + 459.67 = 459.67 °R
This means 0 °F corresponds to 459.67 °R on the Rankine scale.
Conversion Example
- Convert 32 °F to Rankine:
- Start with 32 °F.
- Add 459.67: 32 + 459.67 = 491.67 °R.
- Result: 32 °F = 491.67 °R.
- Convert -40 °F to Rankine:
- Start with -40 °F.
- Add 459.67: -40 + 459.67 = 419.67 °R.
- Result: -40 °F = 419.67 °R.
- Convert 100 °F to Rankine:
- Start with 100 °F.
- Add 459.67: 100 + 459.67 = 559.67 °R.
- Result: 100 °F = 559.67 °R.
- Convert -10 °F to Rankine:
- Start with -10 °F.
- Add 459.67: -10 + 459.67 = 449.67 °R.
- Result: -10 °F = 449.67 °R.

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale using 32 °F as the freezing point of water and 212 °F as boiling. It was developed by Daniel Gabriel Fahrenheit and is primarily used in the United States. The scale divides the interval between freezing and boiling into 180 degrees.
Rankine: Rankine is an absolute temperature scale where zero is absolute zero, the lowest possible temperature. Each Rankine degree equals one Fahrenheit degree. It’s commonly used in thermodynamics in the United States, especially for engineering calculations involving heat and energy.
Conversion FAQs
Is the Rankine scale only used in scientific fields?
Rankine is mostly used in engineering and thermodynamics in the US, rather than everyday temperature measurement. It helps engineers calculate heat and energy more precisely because it measures temperature from absolute zero with Fahrenheit-sized increments.
Why do I add 459.67 to Fahrenheit to get Rankine?
The addition of 459.67 shifts Fahrenheit values so that 0 °R corresponds to absolute zero (-459.67 °F). Since Rankine uses the same degree size as Fahrenheit, the only difference is where zero is placed on the scale.
Can Rankine temperatures be negative?
No, Rankine temperatures cannot be negative because the scale starts at absolute zero, which is the lowest possible temperature. So all Rankine values are zero or positive.
How is converting Fahrenheit to Rankine different from Celsius to Kelvin?
Both Rankine and Kelvin scales begin at absolute zero, but Rankine uses Fahrenheit increments while Kelvin uses Celsius increments. So converting Fahrenheit to Rankine adds 459.67, while Celsius to Kelvin adds 273.15.
Is Rankine used outside of the United States?
Rankine is mostly used in the US for specific engineering applications. Other countries prefer Kelvin for scientific and engineering temperature measurements. Rankine is less common globally but still relevant in some technical contexts.
