0 degrees Fahrenheit is equal to 459.67 degrees Rankine.
The conversion between Fahrenheit and Rankine scales involves adding 459.67 to the Fahrenheit value because Rankine starts at absolute zero, similar to Kelvin but using Fahrenheit increments. So, converting 0°F means shifting it up by 459.67 to align with absolute zero in Rankine.

Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
This formula works because the Rankine scale starts at absolute zero, which is -459.67°F. So, by adding 459.67 to any Fahrenheit temperature, you shift the zero point to absolute zero and keep the size of each degree equal to Fahrenheit degrees.
For example, converting 0°F:
- Start with 0°F
- Add 459.67 to shift to absolute zero
- 0 + 459.67 = 459.67°R
This shows that 0°F corresponds to 459.67 Rankine.
Conversion Example
- Example 1: Convert 32°F to Rankine
- Take 32°F (freezing point of water)
- Add 459.67: 32 + 459.67 = 491.67°R
- So, 32°F equals 491.67 Rankine
- Example 2: Convert -40°F to Rankine
- Take -40°F (where Celsius and Fahrenheit scales meet)
- Add 459.67: -40 + 459.67 = 419.67°R
- So, -40°F equals 419.67 Rankine
- Example 3: Convert 100°F to Rankine
- Take 100°F
- Add 459.67: 100 + 459.67 = 559.67°R
- Therefore, 100°F equals 559.67 Rankine
- Example 4: Convert -10°F to Rankine
- Take -10°F
- Add 459.67: -10 + 459.67 = 449.67°R
- Result: -10°F equals 449.67 Rankine

Conversion Definitions
F (Fahrenheit): Fahrenheit is a temperature scale where the freezing point of water is 32 degrees and boiling point is 212 degrees under standard atmospheric pressure. It was developed in the early 18th century and remains used mainly in the United States for weather, cooking, and industry.
Rankine: Rankine is an absolute temperature scale used in engineering fields where Fahrenheit increments are used but zero starts at absolute zero (-459.67°F). It enables thermodynamic calculations with temperatures expressed on a scale starting from absolute zero.
Conversion FAQs
Why do we add 459.67 to convert Fahrenheit to Rankine?
The addition of 459.67 shifts the Fahrenheit temperature scale so that zero aligns with absolute zero, the lowest possible temperature. Since Rankine scale is absolute, starting at zero Kelvin equivalent in Fahrenheit units, this offset adjusts the zero point correctly.
Can Rankine temperatures be negative?
No, since Rankine starts at absolute zero, which is the lowest possible temperature, Rankine values cannot be negative. Any Fahrenheit value converted to Rankine will result in a positive value equal or greater than zero.
Is Rankine used in everyday temperature measurements?
Rankine is mostly used in scientific and engineering applications, especially thermodynamics, and rarely used for everyday weather or cooking temperatures, where Fahrenheit or Celsius are preferred.
How precise is the conversion from Fahrenheit to Rankine?
The conversion is exact as it relies on a fixed offset. The size of each degree is the same between Fahrenheit and Rankine, so only the zero point shifts. Precision depends on how many decimal places you use when reporting the result.
Does converting 0°F to Rankine mean the same temperature physically?
Yes, converting 0°F to Rankine represents the same physical temperature but expressed on a different scale. Rankine expresses absolute temperature starting from zero, while Fahrenheit uses an arbitrary zero point.
