The temperature 0 °F converts to 459.67 °R (Rankine).
Table of Contents
To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit value because Rankine starts at absolute zero, which is -459.67 °F. So, 0 °F plus 459.67 gives the Rankine equivalent.

Conversion Formula
The formula to convert Fahrenheit (f) to Rankine (R) is:
R = f + 459.67
This works because the Rankine scale starts at absolute zero, which is -459.67 °F. Fahrenheit measures temperature relative to the freezing and boiling points of water, while Rankine is absolute like Kelvin but uses Fahrenheit degrees. By adding 459.67 to a Fahrenheit temperature, you shift the scale to start at zero.
Example: Convert 0 °F to Rankine
- Start with the Fahrenheit value: 0
- Add 459.67: 0 + 459.67 = 459.67
- The result is 459.67 °R
Conversion Example
-
Convert 32 °F to Rankine:
- Take the Fahrenheit value: 32
- Add 459.67: 32 + 459.67 = 491.67
- Answer: 491.67 °R
-
Convert -40 °F to Rankine:
- Start with -40
- Add 459.67: -40 + 459.67 = 419.67
- Result: 419.67 °R
-
Convert 100 °F to Rankine:
- Use 100
- Add 459.67: 100 + 459.67 = 559.67
- Final: 559.67 °R
-
Convert -10 °F to Rankine:
- Start with -10
- Add 459.67: -10 + 459.67 = 449.67
- Output: 449.67 °R

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale based on 32 °F as the freezing point of water and 212 °F as boiling point at standard atmospheric pressure. It uses degrees Fahrenheit, which are increments defined between these fixed points. It is mostly used in the United States.
Rankine (R): Rankine is an absolute temperature scale, like Kelvin, but using Fahrenheit-sized degrees. It sets zero at absolute zero (-459.67 °F), where all thermal motion stops. Rankine is mainly used in thermodynamics and engineering fields that work with Fahrenheit units.
Conversion FAQs
Why add 459.67 to Fahrenheit to convert to Rankine?
Because Rankine scale starts at absolute zero, which corresponds to -459.67 °F, you add this value to shift the Fahrenheit temperature to a zero-based absolute scale. This makes temperatures comparable in absolute terms, useful in physics and engineering.
Can Rankine temperatures be negative?
No, Rankine scale starts at absolute zero, so all Rankine temperatures are zero or positive. Negative values would imply temperatures below absolute zero, which is not physically possible.
Is Rankine used outside of engineering?
Rankine is mostly limited to engineering and thermodynamics where Fahrenheit is the preferred unit. It is not commonly used in daily life or weather reporting, where Celsius or Fahrenheit dominate.
How precise is the conversion from Fahrenheit to Rankine?
The conversion is exact mathematically, just adding 459.67. However, measurement precision depends on the instrument used. The formula itself does not introduce error, only rounding might.
Are Fahrenheit and Rankine increments the same size?
Yes, one degree Fahrenheit equals one degree Rankine in size. The difference is the zero points of each scale; Fahrenheit zero is not absolute zero, but Rankine zero is.
