What is Celsius (°C)?
The degree Celsius (°C) is the SI-derived unit of temperature. It is defined so that 0 °C = 273.15 K exactly, with the same unit increment as the kelvin.
What is Rankine (°Ra)?
The degree Rankine (°R) is an absolute temperature scale using Fahrenheit-sized increments.

Frequently Asked Questions
What is the Rankine scale?
The Rankine scale is an absolute temperature scale like Kelvin, but uses Fahrenheit-sized degrees instead of Celsius-sized degrees. It starts at absolute zero (0°Ra = -273.15°C) and is primarily used in US thermodynamic engineering.
What is 0°C in Rankine?
0°C equals 491.67°Ra. Using the formula: (0 + 273.15) × 9/5 = 491.67°Ra. This is the freezing point of water on the Rankine scale.
What is 100°C in Rankine?
100°C equals 671.67°Ra. This is the boiling point of water. Using the formula: (100 + 273.15) × 9/5 = 671.67°Ra.
How do I convert Celsius to Rankine?
First add 273.15 to the Celsius value to get Kelvin, then multiply by 9/5 to convert to Rankine. The formula is °Ra = (°C + 273.15) × 9/5.
When is the Rankine scale used?
Rankine is used primarily in US engineering thermodynamics, particularly in the aerospace, HVAC, and power generation industries. It is the Fahrenheit equivalent of the Kelvin scale and is required for absolute temperature calculations in the imperial system.
