0 degrees Fahrenheit is equal to 459.67 degrees Rankine.
To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit temperature. This is because the Rankine scale starts at absolute zero, similar to Kelvin, but uses Fahrenheit increments instead of Celsius.

Conversion Formula
The formula to convert Fahrenheit (f) to Rankine (R) is:
R = f + 459.67
This works because the Rankine scale sets zero at absolute zero, which is -459.67°F. Since Fahrenheit degrees are the same size as Rankine degrees, you only need to shift the zero point by adding 459.67.
Example calculation for 0°F:
- Start with 0°F
- Add 459.67 to 0
- 0 + 459.67 = 459.67 Rankine
Conversion Example
- Example 1: Convert 32°F to Rankine
- Start with 32°F
- Add 459.67: 32 + 459.67 = 491.67 Rankine
- Example 2: Convert -40°F to Rankine
- -40°F plus 459.67 equals 419.67 Rankine
- Example 3: Convert 100°F to Rankine
- 100 + 459.67 = 559.67 Rankine
- Example 4: Convert -10°F to Rankine
- -10 + 459.67 = 449.67 Rankine
- Example 5: Convert 212°F to Rankine
- 212 + 459.67 = 671.67 Rankine

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale used mainly in the United States, where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. The scale divides the interval between these points into 180 equal parts called degrees.
Rankine (°R): Rankine is an absolute temperature scale similar to Kelvin but uses Fahrenheit-sized degrees. Zero Rankine represents absolute zero, the lowest possible temperature where molecular motion stops. It is used mostly in thermodynamics and engineering.
Conversion FAQs
Why do I add 459.67 when converting Fahrenheit to Rankine?
Because Rankine starts at absolute zero, which is -459.67°F, adding this value shifts the Fahrenheit temperature scale so that 0 Rankine equals absolute zero. This addition aligns the zero points of both scales while keeping the same degree size.
Can Rankine temperatures be negative?
No, Rankine temperatures cannot be negative. Since the scale begins at absolute zero (0°R), which is the lowest physically possible temperature, all Rankine values are zero or positive.
Is the degree size in Rankine same as Fahrenheit?
Yes, each degree in Rankine is the same size as a degree Fahrenheit. The difference lies only in where zero is set, not in the size of the increment itself.
When would someone prefer Rankine over Fahrenheit?
Rankine is preferred in thermodynamics and engineering fields in the US when absolute temperature measurements are needed with Fahrenheit degree increments, such as in heat transfer calculations.
How is converting Fahrenheit to Rankine different from converting to Kelvin?
Converting Fahrenheit to Rankine involves adding 459.67 to shift the zero point but keeps the degree size same. Converting to Kelvin requires converting Fahrenheit to Celsius first, then adding 273.15, which involves a scaling and shifting step.
