The conversion of 80 Fahrenheit to Rankine results in 560 Rankine.
Since Rankine is an absolute temperature scale starting at absolute zero, converting Fahrenheit to Rankine involves adding 459.67 to the Fahrenheit temperature. Therefore, 80°F plus 459.67 yields the Rankine value.
Conversion Result and Explanation
To convert 80°F to Rankine, simply add 459.67 to the Fahrenheit temperature because Rankine is offset by this value from Fahrenheit. This means 80°F equals 560 Rankine, reflecting an absolute temperature measurement that starts at absolute zero, unlike Fahrenheit that starts at the freezing point of water.

Conversion Formula
The formula to convert Fahrenheit to Rankine is straightforward: Rankine = Fahrenheit + 459.67. This works because the Rankine scale starts at absolute zero, which is 459.67 degrees below the freezing point of water in Fahrenheit. For example, if Fahrenheit is 80, then Rankine is 80 + 459.67 = 560.
Conversion Example
- Convert 100°F to Rankine:
- – Add 459.67 to 100°F.
- – Calculation: 100 + 459.67 = 559.67 Rankine.
- – Result: 100°F equals 559.67 Rankine.
- Convert 32°F to Rankine:
- – Calculation: 32 + 459.67 = 491.67 Rankine.
- – Explanation: 32°F, the freezing point of water, is 491.67 Rankine, showing the offset from absolute zero.
- Convert 212°F to Rankine:
- – Calculation: 212 + 459.67 = 671.67 Rankine.
- – Explanation: The boiling point of water at sea level equals 671.67 Rankine.

Conversion Definitions
Fahrenheit
The Fahrenheit scale measures temperature based on the freezing point of water at 32°F and boiling at 212°F, with 180 degrees between these points, and is primarily used in the United States for everyday temperature readings.
Rankine
The Rankine scale is an absolute temperature system starting at absolute zero, with degrees equal in size to Fahrenheit, used mainly in engineering to relate directly to thermodynamic properties and calculations involving absolute temperature.
Conversion FAQs
How accurate is adding 459.67 to convert Fahrenheit to Rankine?
This method is precisely accurate because Rankine directly offsets Fahrenheit by 459.67 degrees, aligning with absolute zero, making it a simple, reliable conversion for temperature measurements.
Why is the number 459.67 added in the conversion?
This number represents the difference between absolute zero and the freezing point of water in Fahrenheit, aligning the two scales so that absolute zero in Fahrenheit is -459.67°F, and in Rankine, 0°R.
Can I convert Fahrenheit to Rankine manually for any number?
Yes, simply add 459.67 to any Fahrenheit temperature to get the Rankine equivalent, which works for all temperatures on the Fahrenheit scale, making manual conversions straightforward.
