How degree Celsius to degree Réaumur conversion works
Temperature scales are affine: the result needs both a scale factor and a zero-point offset. That is why °C to °Ré cannot be reduced to a simple percentage change.
The right unit depends on the convention used by your industry, country, instrument, or source document.

Frequently asked questions
Frequently Asked Questions
How do I convert degree Celsius to degree Réaumur?
Multiply the degree Celsius value by 0.8 to get it in degree Réaumur. For example, 10 °C = 8 °Ré.
What is 1 °C in °Ré?
1 °C = 0.8 °Ré.
What is 100 °C in °Ré?
100 °C = 80 °Ré.
What is the formula?
Temperature is an affine quantity. The formula depends on the source and target scales; °C → °Ré uses: T(°Ré) = T(°C) × 1 + 54.63, then applies the inverse on the other side.
