The Conversion Formula
Temperature conversions between rankine and réaumur use specific formulas rather than a simple multiplication factor, because temperature scales have different zero points. Use the converter above or the reference table for quick lookups. For example, converting 25 °R gives -207.41 °Re, and converting 100 °R gives -174.08 °Re.
About rankine
The Rankine scale is to Fahrenheit what Kelvin is to Celsius. Proposed by William John Macquorn Rankine in 1859, it is an absolute thermodynamic scale. It starts at absolute zero (0°R), but its degree intervals are equal to Fahrenheit degrees. Water freezes at 491.67°R. It is primarily used in US engineering fields, specifically in thermodynamics and aerospace, where English units are still common. rankine are commonly used in Aerospace engineering (US), Thermodynamics systems, Heat engine calculations, and Gas turbine design.
Absolute zero is 0°R, which is -459.67°F.
About réaumur
The Réaumur scale was defined by René Antoine Ferchault de Réaumur in 1730. He set the freezing point of water at 0° and the boiling point at 80°. Why 80? He believed alcohol expanded 80 parts per 1000 when heated. This scale was once very popular in Europe, especially in France and Russia (it's mentioned often in Dostoevsky's novels). Today, it is mostly obsolete, though still used in some Italian cheese production. réaumur are commonly used in Parmigiano-Reggiano cheese making, Historical literature, 19th-century medical records, and Old candy making recipes.
Water boils at 80°Re.
