1 degree Fahrenheit equals 1 degree Rankine.
The Rankine scale starts at absolute zero, just like Kelvin, but uses Fahrenheit degrees instead of Kelvin. So, when you convert Fahrenheit to Rankine, you just add 459.67 to the Fahrenheit temperature because both scales share the same degree size.
What is the conversion from Fahrenheit to Rankine?
The conversion formula from Fahrenheit to Rankine is straightforward: Rankine temperature equals Fahrenheit temperature plus 459.67. This works because Rankine’s zero point is absolute zero, which is 459.67 degrees below freezing point of water in Fahrenheit. So, to convert, simply add 459.67 to the Fahrenheit value. For example, 0°F converts to 459.67°R, and 100°F becomes 559.67°R.

Conversion Formula
The formula to convert Fahrenheit to Rankine is: R = F + 459.67, where R is Rankine and F is Fahrenheit. This works because Rankine’s zero point is absolute zero, which is 459.67 degrees below the freezing point of water in Fahrenheit. The formula adds this offset to any Fahrenheit temperature to find its Rankine equivalent. For example, if you start with 30°F: 30 + 459.67 = 489.67°R. This method ensures a direct, linear conversion without complex calculations.
Conversion Example
- Convert 20°F to Rankine:
- Start with 20°F
- Add 459.67
- 20 + 459.67 = 479.67°R
- Result is 479.67 Rankine
- Convert -10°F to Rankine:
- Start with -10°F
- Add 459.67
- -10 + 459.67 = 449.67°R
- Result is 449.67 Rankine
- Convert 100°F to Rankine:
- Start with 100°F
- Add 459.67
- 100 + 459.67 = 559.67°R
- Result is 559.67 Rankine
- Convert 0°F to Rankine:
- Start with 0°F
- Add 459.67
- 0 + 459.67 = 459.67°R
- Result is 459.67 Rankine
- Convert 50°F to Rankine:
- Start with 50°F
- Add 459.67
- 50 + 459.67 = 509.67°R
- Result is 509.67 Rankine
