How do I convert Rankine (°R) to Fahrenheit (°F)?

1 rankine equals -458.67 fahrenheit using SI-based conversion and precise factors.

What is the formula to convert Rankine (°R) to Fahrenheit (°F)?

Temperature conversions include an offset (e.g., +273.15 for K, or +/−32 with ratio 5/9 and 9/5).

Is Rankine (°R) to Fahrenheit (°F) conversion exact?

Yes, it follows an exact affine transformation between scales (ratio + offset).

Rankine (°R)	Fahrenheit (°F)
1	-458.67
0.5	-459.17
2.5	-457.17
10	-449.67

Conversion formula

Use the exact 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.

Unit facts

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

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.
