59 degrees Fahrenheit converts to 518.67 Rankine.
The Rankine scale starts at absolute zero, much like Kelvin, but uses Fahrenheit-sized degrees. To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit temperature. This shifts the scale so zero Rankine equals absolute zero, making it useful for thermodynamic calculations.

Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
This formula works because Rankine is an absolute temperature scale using Fahrenheit increments. While Fahrenheit sets its zero at the freezing point of water, Rankine begins at absolute zero, which is −459.67 °F. Adding 459.67 shifts the Fahrenheit value so it aligns with absolute zero, making it a direct way to express temperatures where negative values are avoided.
Example calculation: Converting 59 °F to Rankine.
- Start with 59 °F.
- Add 459.67 to 59: 59 + 459.67 = 518.67.
- The result is 518.67 °R.
Conversion Example
- Convert 32 °F to Rankine:
- 32 + 459.67 = 491.67 °R.
- Water freezing point in Rankine.
- Convert 100 °F to Rankine:
- 100 + 459.67 = 559.67 °R.
- Higher than room temperature.
- Convert 0 °F to Rankine:
- 0 + 459.67 = 459.67 °R.
- Absolute zero offset.
- Convert 75.5 °F to Rankine:
- 75.5 + 459.67 = 535.17 °R.
- Typical warm day value.

Conversion Definitions
Fahrenheit: The Fahrenheit scale is a temperature measurement system where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric conditions. It uses degrees Fahrenheit (°F) as units, primarily used in the United States for everyday temperature readings, weather forecasts, and cooking temperatures.
Rankine: The Rankine scale is an absolute temperature scale similar to Kelvin but uses Fahrenheit increments. Zero Rankine corresponds to absolute zero, the lowest theoretical temperature. It’s mainly used in engineering fields, especially thermodynamics in the US, where temperatures must be expressed on an absolute scale.
Conversion FAQs
Can Rankine temperatures be negative like Fahrenheit?
No, Rankine temperatures cannot be negative because the scale starts at absolute zero (0 °R), which is the lowest physical temperature possible. Since Rankine uses Fahrenheit-sized increments but starts at absolute zero, all Rankine values are zero or positive.
Why add exactly 459.67 to convert Fahrenheit to Rankine?
The number 459.67 represents the offset between the Fahrenheit zero point and absolute zero. Since Rankine’s zero point is absolute zero, adding 459.67 shifts the Fahrenheit scale so that 0 °R matches absolute zero, making the Rankine scale absolute and useful for thermodynamic computations.
Is Rankine used outside the US?
Rankine is mostly used in the United States, especially in engineering and thermodynamics. Other countries tend to use Kelvin for absolute temperature measurements, although Rankine has the advantage of using Fahrenheit-sized units, making it more intuitive in contexts where Fahrenheit is common.
Does converting 59 °F to Rankine require any special tools?
No special tools are needed; the conversion is straightforward by adding 459.67 to the Fahrenheit temperature. This can be done mentally for approximate results or with a calculator for precise values.
How precise is the conversion from Fahrenheit to Rankine?
The conversion is exact in theory because it’s a simple linear offset. However, slight measurement errors in temperature readings or rounding may affect precision. The formula itself doesn’t introduce any uncertainty.
