Our celsius to rankine calculator is designed to automatically convert temperatures from the Celsius scale to the Rankine scale using conversion formula: °R = (°C + 273.15) × (9/5).
The Rankine scale, developed by Scottish engineer William John Macquorn Rankine in 1859, is an absolute temperature scale primarily used in engineering applications and thermodynamic calculations in the United States. Similar to the Kelvin scale, Rankine begins at absolute zero but uses degree intervals identical to the Fahrenheit scale.

Celsius to Rankine Conversion Formula
The precise formula for converting °C to °R is:
°R = (°C + 273.15) × (9/5)Where:
- °R denotes the temperature in Rankine
- °C represents the temperature in Celsius
- 273.15 is the Kelvin offset (converting Celsius to absolute scale)
- 9/5 represents the ratio of Fahrenheit/Celsius degree sizes
To convert 20°C to Rankine:
- First add 273.15: 20 + 273.15 = 293.15
- Then multiply by 9/5: 293.15 × (9/5) = 527.67°R
How to Convert Celsius to Rankine?
- First Step: Convert to absolute scale
- Add 273.15 to the Celsius temperature
- 30°C + 273.15 = 303.15
- Second Step: Adjust for degree size
- Multiply by 9/5 to convert to Rankine
- 303.15 × (9/5) = 545.67°R
What is 100 Degrees Celsius to Rankine?
Start with 100°C (water’s boiling point)
Convert to absolute scale: 100 + 273.15 = 373.15
Apply the 9/5 conversion factor: 373.15 × (9/5) = 671.67°R
This value represents the boiling point of water on the Rankine scale under standard atmospheric pressure (1 atm), making it a crucial reference point in thermodynamic calculations.
