What is a degree Rankine?
Rankine is an absolute scale that uses Fahrenheit-sized degrees. It starts at absolute zero, so 0 °R equals −459.67 °F.
What is a degree Celsius?
The Celsius scale places 0 °C at the freezing point of water and 100 °C at its boiling point at standard pressure. It is the everyday temperature scale in almost every country.
