Réaumur to Fahrenheit: Definition, History, Historical Uses, and Examples
Definition
Réaumur (°Ré) is a historical temperature scale where 0°Ré = freezing point of water and 80°Ré = boiling point of water at 1 atm. Fahrenheit (°F) is the imperial temperature scale where 32°F = freezing and 212°F = boiling point of water. The conversion formula is: °F = (°Ré × 9/4) + 32.
Origin or History
The Réaumur scale was proposed by French naturalist René Antoine Ferchault de Réaumur in 1730. It was designed as a practical temperature measurement system, dividing the temperature range between freezing and boiling water into 80 degrees. The scale was widely used in Europe, particularly in France, Germany, and Russia, until the 19th century.
Historical Use
- European Science: Official temperature scale used throughout Europe for scientific research.
- Wine Making: Temperature control in wine production and fermentation processes.
- Cheese Production: Temperature monitoring in dairy and cheese making.
- Industrial Processes: Temperature control in manufacturing and food processing.
- Meteorology: Weather recording and climate studies in Europe.
