Convert Temperature Units Online with Reaumur (°Ré) to Celsius (°C) Conversion

Convert Reaumur to Celsius using the exact conversion factor. This page provides the formula, reference values, and practical context for engineering, technical calculations, and professional measurement use.

Conversion Formula

°C = °Ré × 5/4

Temperature conversions use an offset formula, not a single multiplier. Apply the relationship shown above (for example Reaumur (°Ré) to Celsius (°C)) so absolute scale differences (such as the 273.15 K offset for Celsius) are handled correctly.

Example

Convert 1 Re to C.

• Step 1: Write the formula: °C = °Ré × 5/4
• Step 2: Substitute: Re = 1
• Step 3: Result: 1.25 C

So, 1 Re = 1.25 C.

About the Units
