Samantha NicoleThe conversion of 0 degrees Fahrenheit (f) to degrees Rankine (r) results in 459.67 R.
Rankine is an absolute temperature scale, starting at absolute zero, just like Kelvin but using Fahrenheit degrees. To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit value, reflecting the offset from absolute zero.

Conversion Formula
The formula to convert Fahrenheit (f) to Rankine (r) is:
r = f + 459.67
This formula works because the Rankine scale starts at absolute zero, just like Kelvin, but uses Fahrenheit degrees. Since absolute zero is -459.67°F, adding 459.67 shifts the Fahrenheit scale to start from zero at absolute zero.
For example, converting 0°F:
- Start with 0°F.
- Add 459.67 to 0.
- Result is 459.67 R.
Conversion Example
- Convert 32°F to Rankine:
- Take 32°F.
- Add 459.67 to get 32 + 459.67 = 491.67 R.
- So, 32°F equals 491.67 R.
- Convert -40°F to Rankine:
- Start -40°F.
- Add 459.67: -40 + 459.67 = 419.67 R.
- This means -40°F is 419.67 R.
- Convert 100°F to Rankine:
- Begin with 100°F.
- Add 459.67: 100 + 459.67 = 559.67 R.
- Therefore, 100°F equals 559.67 R.

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale based on 32°F as the freezing point of water and 212°F as boiling point, dividing the range into 180 degrees. Mostly used in the United States for everyday temperature measurement, it uses degrees that are not part of an absolute scale.
Rankine (r): Rankine is an absolute temperature scale using Fahrenheit degrees. Its zero point is absolute zero (-459.67°F), making it useful in thermodynamics and engineering fields requiring absolute temperatures. Rankine is like Kelvin but scaled with Fahrenheit degrees.
Conversion FAQs
Why does converting 0°F to Rankine add 459.67?
Because Rankine starts at absolute zero, which is -459.67°F, you add 459.67 to shift the Fahrenheit temperature scale so absolute zero is zero Rankine. This offset is needed since Fahrenheit uses an arbitrary zero point.
Can Rankine values be negative like Fahrenheit?
No, Rankine values cannot be negative because Rankine is absolute temperature scale starting at zero for absolute zero. Since absolute zero is the lowest possible temperature, Rankine values are always zero or positive.
Is Rankine used outside scientific fields?
Rankine scale is rare outside engineering and thermodynamics. It is mostly used in American engineering contexts where absolute temperatures in Fahrenheit degrees are necessary, but not common in general weather or daily use.
How precise is the conversion from Fahrenheit to Rankine?
The conversion is exact mathematically because it involves only adding a constant 459.67. Precision depends on decimal places used but the formula itself has no approximation.
Why use Rankine instead of Kelvin?
Rankine is more convenient than Kelvin when working with systems using Fahrenheit for temperature differences or measurements. It preserves the Fahrenheit scale increments, making calculations consistent with Fahrenheit-based systems.
