The degree Celsius is a unit of temperature on the Celsius scale, where 0 °C is the freezing point and 100 °C is the boiling point of water at standard atmospheric pressure.

The degree Réaumur is a historical temperature scale where water freezes at 0 °Ré and boils at 80 °Ré at standard pressure.

Where is Celsius used in everyday life?

Weather reports, cooking temperatures, body temperature (37 °C normal), refrigerator settings (2–4 °C), and industrial processes.

What are common mistakes when converting Celsius?

Forgetting the °C × 9/5 + 32 offset when converting to Fahrenheit. Also, assuming 0 °C = 0 K (actually 0 °C = 273.15 K).

How to Convert Celsius to Réaumur

To Fahrenheit: °F = °C × 9/5 + 32. To Kelvin: K = °C + 273.15. To Rankine: °R = (°C + 273.15) × 9/5.

°C = K − 273.15. The Celsius and Kelvin scales have identical degree sizes — they differ only by an offset of 273.15.

For example, 1 Celsius (°C) = 0.8 Réaumur (°Ré).
