What is the Rankine temperature scale?

Rankine (°R) is an absolute temperature scale used primarily in engineering, especially in the United States. It starts at absolute zero like Kelvin but uses Fahrenheit-sized degrees. 0°R = -459.67°F = -273.15°C.

How do you convert Celsius to Rankine?

To convert Celsius to Rankine, add 273.15 to the Celsius temperature, then multiply by 9/5. Formula: °R = (°C + 273.15) × 9/5. For example, 100°C = (100 + 273.15) × 9/5 = 671.67°R.

When is the Rankine scale used?

The Rankine scale is primarily used in thermodynamic engineering calculations in the United States, particularly in fields like HVAC, aerospace, and chemical engineering where absolute temperatures in Fahrenheit-based units are needed.
