Celsius to Reaumur Calculator

Do you need a quick and accurate way to convert Celsius to Reaumur? Our Celsius to Réaumur Calculator provides instant results with just one click, eliminating the hassle of manual calculations. Whether you are a student, researcher, historian, or professional in food production, this calculator ensures precise conversions every time.

Understanding Celsius and Reaumur

Celsius (°C): The Celsius scale, also known as the Centigrade scale, is the most widely used temperature measurement unit in the world.
Water freezes at 0°C
Water boils at 100°C (under standard atmospheric pressure)
Celsius is used globally in science, weather forecasts, healthcare, cooking, and education.

Réaumur (°Re or °R): The Reaumur scale is an older temperature unit developed by René Antoine Ferchault de Réaumur in the 18th century.
Water freezes at 0°Re
Water boils at 80°Re
It was historically popular in Europe (especially France, Germany, and Russia), and it is still sometimes used in food production (cheese and syrup making), brewing, and historical research.

👉 Conversion Value: Because 100°C corresponds to 80°Re, the relationship between the two scales is simple and proportional.

Formula to Convert Celsius to Réaumur

Steps:
Take the Celsius temperature value.
Multiply it by 4/5 (or 0.8).
The result is the equivalent temperature in Réaumur.

Examples of Conversion

Convert 0°C to Reaumur

✅ So, 0°C = 0°Re

Convert 25°C to Reaumur

✅ So, 25°C = 20°Re

Convert 50°C to Reaumur

✅ So, 50°C = 40°Re

Convert 80°C to Reaumur

✅ So, 80°C = 64°Re

Convert 100°C to Reaumur

✅ So, 100°C = 80°Re (boiling point of water in Reaumur scale)
