Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
This works because Rankine starts at absolute zero, which is −459.67°F. Both Rankine and Fahrenheit scales use the same size increment per degree, so only an offset is needed. You don’t multiply or divide, just add 459.67.
Example:
- Convert 0°F to Rankine.
- Add 459.67 to 0: 0 + 459.67 = 459.67°R.
- So, 0°F equals 459.67°R.
Conversion Example
- Convert 32°F to Rankine:
- Start with 32°F.
- Add 459.67: 32 + 459.67 = 491.67°R.
- Therefore, 32°F equals 491.67°R.
- Convert -40°F to Rankine:
- Begin with -40°F.
- Add 459.67: -40 + 459.67 = 419.67°R.
- Result is -40°F equals 419.67°R.
- Convert 100°F to Rankine:
- Take 100°F.
- Add 459.67: 100 + 459.67 = 559.67°R.
- So, 100°F is 559.67°R.
- Convert 212°F to Rankine:
- Start with 212°F.
- Add 459.67: 212 + 459.67 = 671.67°R.
- Therefore, 212°F equals 671.67°R.

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It divides the interval between freezing and boiling into 180 equal parts called degrees. Used primarily in the United States.
Rankine: The Rankine scale measures temperature starting at absolute zero, like Kelvin, but uses Fahrenheit-sized degrees. Zero Rankine equals absolute zero, the lowest limit of thermodynamic temperature, making it useful in engineering fields involving thermodynamics in Fahrenheit units.
Conversion FAQs
Is Rankine the same as Kelvin but in Fahrenheit units?
Yes, Rankine scale is similar to Kelvin because both start at absolute zero, but Rankine degrees are the same size as Fahrenheit, while Kelvin uses Celsius-sized degrees. So Rankine fits better with Fahrenheit-based systems.
Why does converting Fahrenheit to Rankine only involve adding 459.67?
Because Rankine scale starts at absolute zero, which is −459.67°F, adding this offset shifts the Fahrenheit temperature to absolute scale. Since both use the same degree size, no multiplication is needed, just an addition.
Can Rankine values be negative?
No, Rankine scale starts at absolute zero (0°R), the lowest physically possible temperature, so Rankine values cannot be negative. Fahrenheit, however, can go below zero.
How precise is converting Fahrenheit to Rankine by simply adding 459.67?
The conversion is exact in terms of scale offset, but real-world measurements might have errors. The constant 459.67 is defined to match absolute zero in Fahrenheit, so the formula is precise for temperature conversions.
When should I use Rankine instead of Fahrenheit?
Rankine is used in scientific and engineering fields where absolute temperature measurements are needed, especially in thermodynamics calculations involving Fahrenheit-based units. Fahrenheit is more common for everyday weather or cooking temperatures.
