Rankine (°R)
Temperature
Traceable to the kelvin, defined by fixing the Boltzmann constant at 1.380 649 × 10⁻²³ J/K. Celsius and Fahrenheit are exact affine transforms of the kelvin scale.

How to Convert Rankine to Fahrenheit
This conversion uses an offset formula, so it cannot be described by a single multiplication factor.
Formula: °F = °R - 459.67
Reverse: °R = °F + 459.67
Step-by-Step Example
- Start with your value in Rankine. For example: 5 °R
- Apply °F = °R - 459.67
- The result is: -454.67 °F
About Rankine
The Rankine scale is an absolute temperature scale using Fahrenheit-sized degrees: 0 °R is absolute zero and water freezes at 491.67 °R.
Common uses: US thermodynamics, combustion engineering.
About Fahrenheit
The Fahrenheit scale sets 32°F as the freezing point and 212°F as the boiling point of water. It is primarily used in the United States.
Fun Fact: Daniel Fahrenheit chose 96°F as his upper reference point, based on human body temperature (which he measured slightly inaccurately).
Common uses: weather (US), cooking (US), HVAC.
