How to convert fahrenheit (°f) to rankine (°r)

Temperature scales combine ratios and offsets. Kelvin is absolute (no negative values), Celsius offsets Kelvin by 273.15, and Fahrenheit uses a different step and zero point. Because offsets exist, temperature conversions require both a factor and an addition/subtraction.

This converter calculates Fahrenheit (°F) to Rankine (°R) values by using the correct conversion rule for the Temperature category. For linear units, standardized factors are used. For temperature, the calculator applies the proper formula with offsets.

Conversion formula

Use the following formula:

°R = °F + 459.67

Temperature conversions use exact affine formulas (ratio + offset).

Common mistakes

  • Using only a ratio (×1.8 or ×0.555…) without adding/subtracting the offset (±32, +273.15).
  • Rounding too early; convert first, then round to the desired precision.

Unit facts

  • Fahrenheit (°F): Fahrenheit (°F) is an offset scale: 32 °F freezing, 212 °F boiling of water (1 atm).
  • Rankine (°R): Rankine (°R) is an absolute scale using Fahrenheit-sized degrees; used in some engineering contexts.

About Fahrenheit (°F)

Fahrenheit (°F)

Offset scale with 32 °F as water’s freezing point and 212 °F as boiling at 1 atm. Offers finer granularity per degree for everyday weather reporting in the US.

History: Proposed by Daniel G. Fahrenheit in the 18th century; based on calibration points available at the time.

About Rankine (°R)

Rankine (°R)

Absolute scale using Fahrenheit-sized degrees. Useful in aerospace and thermodynamic calculations within imperial frameworks.

History: Introduced by William Rankine in the 19th century as an analogue of Kelvin for Fahrenheit users.

Frequently asked questions

How do I convert Fahrenheit (°F) to Rankine (°R)?
Enter the temperature in Fahrenheit (°F) and the calculator will apply the exact conversion formula to return the result in Rankine (°R).
Is Fahrenheit (°F) to Rankine (°R) conversion exact?
Yes. Temperature conversions use exact affine formulas with a ratio and an offset.
Why does temperature conversion depend on the input value?
Unlike linear unit conversions, temperature scales do not start at the same zero point, so the conversion includes an offset.
