66 degrees Fahrenheit is equal to 525.67 degrees Rankine.
The conversion from Fahrenheit to Rankine involves adding 459.67 to the Fahrenheit temperature. This is because the Rankine scale starts at absolute zero, just like Kelvin, but uses Fahrenheit-sized degrees instead of Celsius-sized ones. By shifting the zero point, we convert the temperature properly.

Conversion Formula
The formula to convert Fahrenheit (f) to Rankine (R) temperature scale is:
R = f + 459.67
Since Fahrenheit degrees and Rankine degrees are the same size, only the zero point shifts. Fahrenheit zero is at -459.67 R, so we add this value to get Rankine. This works because Rankine starts at absolute zero, which is −459.67 °F.
For example, converting 66 °F to Rankine:
- Start with 66 °F
- Add 459.67: 66 + 459.67 = 525.67
- So, 66 °F = 525.67 °R
Conversion Example
- Convert 32 °F to Rankine:
- Take 32 °F
- Add 459.67: 32 + 459.67 = 491.67 °R
- Convert 100 °F to Rankine:
- Start with 100 °F
- Add 459.67: 100 + 459.67 = 559.67 °R
- Convert 0 °F to Rankine:
- Take 0 °F
- Add 459.67: 0 + 459.67 = 459.67 °R
- Convert -40 °F to Rankine:
- Begin with -40 °F
- Add 459.67: -40 + 459.67 = 419.67 °R
- Convert 212 °F to Rankine:
- Start with 212 °F
- Add 459.67: 212 + 459.67 = 671.67 °R

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It is mainly used in the United States and some Caribbean countries. The scale divides the interval between freezing and boiling into 180 equal parts called degrees Fahrenheit.
Rankine (°R): Rankine is an absolute temperature scale used in engineering systems where Fahrenheit is common. It starts at absolute zero, the lowest possible temperature, and increases in increments the same size as Fahrenheit degrees. Rankine is used especially in thermodynamics to measure absolute temperature.
Conversion FAQs
Why do we add 459.67 when converting Fahrenheit to Rankine?
Because Rankine is an absolute temperature scale, it starts at absolute zero, which is −459.67 °F. Adding 459.67 shifts the Fahrenheit temperature to the Rankine scale, aligning zero Rankine with absolute zero, but keeps the degree size same.
Is Rankine used outside the United States?
Rankine scale is primarily used in the United States for thermodynamics, especially in engineering fields dealing with heat and energy. Other countries prefer Kelvin for absolute temperatures, but Rankine remains useful where Fahrenheit is standard.
Can the Fahrenheit to Rankine conversion result in negative values?
No, because Rankine starts at absolute zero, which corresponds to −459.67 °F. Any Fahrenheit temperature above -459.67 will convert to a positive Rankine value. Temperatures below absolute zero are not physically meaningful.
Do Fahrenheit and Rankine degrees represent the same temperature intervals?
Yes, both Fahrenheit and Rankine scales use degrees of the same size. The only difference is their zero points. This means adding or subtracting values between temperatures is consistent across these scales.
How precise is the conversion between Fahrenheit and Rankine?
The conversion is exact mathematically, since it’s a simple addition of 459.67. However, measurement precision depends on instruments used; the formula itself doesn’t introduce errors.
