Conversion Formula
The formula to convert Fahrenheit to Rankine adds 459.67 to the Fahrenheit temperature: R = F + 459.67. Because Rankine starts at absolute zero like Kelvin but uses Fahrenheit units, this addition shifts the scale so that absolute zero is 0 Rankine. For example, 70°F + 459.67 = 530.67 R.
Conversion Example
- Convert 50°F to Rankine:
- Start with the formula: R = F + 459.67.
- Plug in 50: R = 50 + 459.67.
- Calculate: R = 509.67 Rankine.
- So, 50°F equals 509.67 Rankine.
- Convert 100°F to Rankine:
- Rewrite the formula: R = 100 + 459.67.
- Add: R = 559.67 Rankine.
- Thus, 100°F is 559.67 Rankine.
- Convert 32°F to Rankine:
- Apply formula: R = 32 + 459.67.
- Result: R = 491.67 Rankine.
- Therefore, 32°F equals 491.67 Rankine.

Conversion Definitions
Fahrenheit
Fahrenheit is a temperature scale where 32°F is the freezing point of water and 212°F is the boiling point at standard atmospheric pressure; it is used mainly in the United States for everyday temperature readings, based on a scale established by Daniel Gabriel Fahrenheit.
Rankine
Rankine is an absolute temperature scale used mainly in thermodynamics, where 0°R is absolute zero, and each degree Rankine equals one Fahrenheit degree; it is obtained by adding 459.67 to Fahrenheit temperatures, aligning with the Kelvin scale but in Fahrenheit units.
Conversion FAQs
Why do I need to add 459.67 to Fahrenheit to get Rankine?
Because Rankine starts at absolute zero, which is -459.67°F, adding 459.67 shifts the scale so that the freezing point of water at 32°F becomes 491.67°R, making the two scales compatible and allowing direct conversions without multiplication.
Can I convert Fahrenheit to Kelvin directly?
Yes, but it involves subtracting 32 from Fahrenheit, multiplying by 5/9, then adding 273.15. Unlike Rankine, Kelvin starts at absolute zero in Celsius, so the conversion includes an additional step after adjusting for the temperature scale difference.
Does converting 70°F to Rankine help in thermodynamic calculations?
Absolutely, because Rankine is an absolute scale. Using Rankine allows calculations involving heat and energy where absolute temperatures are necessary, such as in entropy or thermodynamic efficiency calculations, making it a practical conversion for engineering tasks.
