Convert Rankine (°R) (rankine) to Fahrenheit (°F) (fahrenheit)
Category: Temperature
1 rankine = -458.67 fahrenheit
High-precision rounding: 6 decimals
How to convert rankine (°r) to fahrenheit (°f)
We convert by pivoting through the SI base unit for Temperature and applying exact factors where applicable.

Examples
Formula: °F = °R − 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.
About Temperature
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.
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.
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.
