Rankine to Réaumur Converter

About Rankine (°R) and Réaumur (°Ré) Units

Rankine (°R) is a temperature scale named after the Scottish engineer William Rankine. It is mainly used in engineering and thermodynamics, especially in the United States. The Rankine scale uses absolute zero as its starting point, so 0°R equals absolute zero, and water freezes at 491.67°R. It is commonly used in heat engine calculations, thermodynamic cycles, and aerospace engineering where absolute temperatures are required in Fahrenheit increments. Réaumur (°Re) is a temperature scale named after the French scientist René Antoine Ferchault de Réaumur. In this scale, water freezes at 0°Re and boils at 80°Re. It was historically used in Europe for scientific work, brewing, and some industrial processes. Although it is largely replaced by Celsius today, Réaumur is still referenced in historical recipes, old scientific texts, and specialty brewing measurements.
