Celsius (°C)
Temperature
t/°C = T/K − 273.15. The degree Celsius has exactly the same magnitude as the kelvin.

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 Celsius to Rankine
This conversion uses an offset formula, so it cannot be described by a single multiplication factor.
Formula: °R = (°C + 273.15) × 9/5
Reverse: °C = (°R - 491.67) × 5/9
Step-by-Step Example
- Start with your value in Celsius. For example: 5 °C
- Apply °R = (°C + 273.15) × 9/5
- The result is: 500.67 °R
About Celsius
The Celsius scale sets 0°C as the freezing point and 100°C as the boiling point of water at standard pressure. It is used by most countries worldwide.
Fun Fact: Anders Celsius originally proposed a scale where 100° was freezing and 0° was boiling—it was later reversed!
Common uses: weather, cooking, science.
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.
