Celsius to Reaumur Converter
Convert Celsius to Reaumur quickly with our free temperature converter. Perfect for interpreting historical European temperature records, traditional cheesemaking and cooking, and understanding the historical temperature scale once common across Europe.
Why Convert Celsius to Reaumur?
The Reaumur scale was widely used across Europe from the 18th century until the mid-20th century. While largely replaced by Celsius today, Reaumur still appears in historical scientific records, traditional European cheesemaking (especially Italian and Swiss), some culinary traditions, and antique thermometers. Converting Celsius to Reaumur helps interpret these historical and traditional contexts.
How the Conversion Works
The conversion from Celsius to Reaumur multiplies by 0.8 (or 4/5): °Re = °C × 0.8. Both scales set 0° at the freezing point of water, but Reaumur sets the boiling point at 80° instead of 100°. This makes each Reaumur degree 1.25 times larger than a Celsius degree.
When to Use This Converter
Use this Celsius to Reaumur converter when reading historical European scientific documents, following traditional cheesemaking recipes (especially Parmigiano-Reggiano), interpreting antique thermometer readings, researching 18th-19th century temperature records, or understanding historical meteorological data from Europe.
