About converting Rankine to Celsius

Converting Rankine to Celsius is a common temperature conversion. One rankine (°R) equals -272.6 celsius (°C). Rankine is an absolute temperature scale using Fahrenheit degree intervals, used in some US engineering applications.

This conversion is commonly needed for weather and travel planning, cooking and baking, scientific experiments. Celsius is used in most countries worldwide and in all scientific applications.

To put rankine in perspective: absolute zero (0 °R). In celsius, common references include water freezes (0 °C).

Real-world examples
Rankine (°R)
  • absolute zero (0 °R)
  • water freezes (491.67 °R)
  • water boils (671.67 °R)
Celsius (°C)
  • water freezes (0 °C)
  • a comfortable room (21 °C)
  • water boils (100 °C)
Did you know?

The Celsius scale was invented by Swedish astronomer Anders Celsius in 1742, but he originally set 0° as boiling and 100° as freezing — it was later reversed.
