Rankine Temperature Conversion Formulas

$$\text{Kelvin (K)} = \frac{°R}{1.8}$$ $$\text{Celsius (°C)} = \frac{°R – 491.67}{1.8}$$ $$\text{Fahrenheit (°F)} = °R – 459.67$$ $$\text{Newton (°N)} = \frac{(°R – 491.67)}{5.45454545}$$ $$\text{Delisle (°De)} = (373.15 – \frac{°R}{1.8}) \times \frac{3}{2}$$ $$\text{Reaumur (°Re)} = \frac{°R – 491.67}{2.25}$$ $$\text{Rømer (°Rø)} = \left( \frac{°R – 491.67}{2.25} \times \frac{21}{32} \right) + 7.5$$

These formulas help convert Rankine to all major temperature units, both modern and historical, commonly used in scientific, industrial, and educational contexts.

Rankine is an absolute temperature scale primarily used in thermodynamic equations and engineering applications, particularly in the U.S. It operates similarly to Kelvin but uses Fahrenheit-sized degrees. This converter allows you to accurately transform Rankine into Celsius, Fahrenheit, Kelvin, and alternative units like Delisle, Newton, Reaumur, and Rømer — enabling seamless unit integration across various systems and scientific disciplines.
