The temperature 66°F converts to 525.67° Rankine.
The conversion from Fahrenheit to Rankine involves adding 459.67 to the Fahrenheit value, because Rankine is an absolute temperature scale based on Fahrenheit increments. So, 66 plus 459.67 gives the Rankine equivalent.

Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
Rankine scale starts at absolute zero, like Kelvin but using Fahrenheit degree sizes. Adding 459.67 shifts the Fahrenheit scale so zero Rankine is absolute zero. This means each degree Rankine equals one Fahrenheit degree, just starting from absolute zero.
Step-by-step example:
- Given 66°F
- Add 459.67 to 66, so: 66 + 459.67 = 525.67°R
- This means 66°F is 525.67 degrees Rankine.
Conversion Example
- Example: Convert 32°F to Rankine
- Take 32 (Fahrenheit)
- Add 459.67: 32 + 459.67 = 491.67°R
- Result: 32°F equals 491.67 Rankine
- Example: Convert 100°F to Rankine
- Start with 100°F
- Add 459.67: 100 + 459.67 = 559.67°R
- So, 100°F is 559.67 Rankine
- Example: Convert 0°F to Rankine
- Value: 0°F
- Add 459.67: 0 + 459.67 = 459.67°R
- Thus, 0°F equals 459.67 Rankine
- Example: Convert 212°F to Rankine
- Given 212°F
- Add 459.67: 212 + 459.67 = 671.67°R
- Therefore, 212°F equals 671.67 Rankine

Conversion Definitions
Fahrenheit (°F): Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. The scale was created by Daniel Gabriel Fahrenheit in 1724 and is most commonly used in the United States for everyday temperature measurements.
Rankine (°R): Rankine is an absolute temperature scale based on Fahrenheit increments. Zero Rankine is absolute zero, the coldest possible temperature. Each degree Rankine equals one degree Fahrenheit, making it useful in thermodynamics and engineering calculations involving temperature in the Imperial system.
Conversion FAQs
Why is 459.67 added to Fahrenheit when converting to Rankine?
The number 459.67 represents the offset between the Fahrenheit scale and absolute zero. Rankine starts from absolute zero, so adding 459.67 shifts the Fahrenheit value to start at zero Rankine. This makes the Rankine scale absolute and compatible with thermodynamic calculations.
Can Rankine temperatures be negative?
No, Rankine temperatures cannot be negative because zero Rankine is absolute zero, the lowest possible temperature. Temperatures below this are physically impossible according to current scientific understanding.
Is Rankine commonly used outside scientific fields?
Rankine is rarely used outside specific scientific and engineering fields, mostly in thermodynamics within the United States. For everyday temperature, Fahrenheit or Celsius are more common.
How does Rankine compare to Kelvin?
Rankine and Kelvin both start at absolute zero, but Kelvin uses Celsius degree sizes while Rankine uses Fahrenheit degree sizes. This makes conversions between Rankine and Kelvin require scaling and offset adjustments.
Can I convert Rankine back to Fahrenheit?
Yes, converting Rankine to Fahrenheit is done by subtracting 459.67 from the Rankine value. This reverses the offset added when converting Fahrenheit to Rankine.
