0 degrees Fahrenheit equals 459.67 degrees Rankine.
The Rankine scale starts at absolute zero, so to convert Fahrenheit to Rankine, you add 459.67. Since 0°F is far below zero on the Fahrenheit scale, adding this offset shifts the value to the Rankine scale correctly.

Conversion Formula
The conversion from Fahrenheit (f) to Rankine (r) is simple: add 459.67 to the Fahrenheit value. This works because Rankine is an absolute temperature scale like Kelvin but uses Fahrenheit increments instead of Celsius. The zero point of Rankine is absolute zero, which is −459.67°F.
Formula: r = f + 459.67
How it works: Fahrenheit scale starts at the freezing point of water at 32°F, while Rankine starts at absolute zero. So by adding 459.67, you shift the Fahrenheit temperature to the absolute scale Rankine uses.
Example: To convert 0°F, add 459.67:
- r = 0 + 459.67
- r = 459.67°R
Conversion Example
- Convert 32°F to Rankine:
- Add 459.67: 32 + 459.67 = 491.67°R
- This means 32°F is 491.67°R
- Convert -40°F to Rankine:
- Add 459.67: -40 + 459.67 = 419.67°R
- So -40°F equals 419.67°R
- Convert 100°F to Rankine:
- Add 459.67: 100 + 459.67 = 559.67°R
- Resulting in 559.67°R
- Convert -10.5°F to Rankine:
- Add 459.67: -10.5 + 459.67 = 449.17°R
- This means -10.5°F = 449.17°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 uses increments called degrees Fahrenheit, and is commonly used in the United States for weather forecasts, cooking, and industrial measurements.
Rankine (r): Rankine is an absolute temperature scale mostly used in thermodynamics within the United States. It starts at absolute zero, like Kelvin, but increments are equal to Fahrenheit degrees. Rankine values are obtained by adding 459.67 to the Fahrenheit temperature.
Conversion FAQs
Why does the Rankine scale add 459.67 to Fahrenheit values?
Because Rankine is an absolute temperature scale, it starts at absolute zero, which equals −459.67°F. Adding 459.67 shifts the Fahrenheit value so that absolute zero corresponds to zero Rankine, keeping increments consistent with Fahrenheit degrees.
Can I convert negative Fahrenheit temperatures to Rankine without issues?
Yes, negative Fahrenheit temperatures can be converted by adding 459.67. Since Rankine scale starts at absolute zero, all Rankine temperatures are positive. Negative Fahrenheit values become positive Rankine values after conversion.
Is Rankine scale used widely outside the US?
Rankine scale is primarily used in the United States, especially in engineering and thermodynamics. Other countries prefer Kelvin, which uses Celsius increments, but Rankine remains useful in systems using Fahrenheit.
How precise is the conversion formula for practical use?
The formula r = f + 459.67 is exact for converting Fahrenheit to Rankine. Precision depends on how many decimal places you use, but for most practical purposes four decimal places is more than enough.
Does converting temperature affect physical properties measured at those temperatures?
The conversion merely changes the scale for temperature representation; physical properties like pressure or volume related to temperature must consider absolute scales like Rankine or Kelvin. Using Rankine helps in thermodynamic calculations involving absolute temperatures.
