Whether you’re working in thermodynamics, food technology, historical research, or academic studies, this tool makes it simple to convert between one of the most technical temperature scales (Rankine) and one of the more historical ones (Reaumur).
Understanding Rankine and Réaumur
Rankine (°R or °Ra): Rankine is an absolute temperature scale used mainly in the United States. It works like the Kelvin scale but uses Fahrenheit-sized degrees.
On this scale:
Absolute zero = 0 °R
Water freezes at 491.67 °R
Water boils at 671.67 °R
Rankine is widely used in aerospace engineering, thermodynamics, and power plant analysis.
Reaumur (°Re): The Réaumur scale was developed in the 18th century by René Antoine Ferchault de Réaumur.
On this scale:
Water freezes at 0°Re
Water boils at 80°Re
Once popular across Europe, the Reaumur scale is now mostly used in food production industries (cheese-making, brewing, and syrup making) and historical scientific research.
👉 Conversion Value: Since Rankine and Reaumur are based on different systems, the conversion requires multiple steps: first converting Rankine to Celsius, then Celsius to Reaumur.
Formula to Convert Rankine to Reaumur
Examples of Conversion
Convert 491.67 °R to Reaumur
✅ So, 491.67 °R = 0°Re (freezing point of water).
Convert 671.67 °R to Reaumur
✅ So, 671.67 °R = 80°Re (boiling point of water).
Convert 558 °R to Reaumur
✅ So, 558 °R = 29.48°Re (close to human body temperature).
Convert 419.67 °R to Reaumur
✅ So, 419.67 °R = -32°Re (very cold conditions).
Convert 800 °R to Reaumur
✅ So, 800 °R = 137.04°Re (very high temperature).
Convert 150 °R to Reaumur
✅ So, 150 °R = -151.85°Re (extreme cryogenic conditions).
