As we know One °C is equal to 0.8 °Re (1 °C = 0.8 °Re).

To convert Degree Centigrade to Degree Reaumur, multiply your °C figure by 0.8.

Example : convert 25 °C to °Re:

25 °C = 25 × 0.8 °Re = °Re

To convert Degree Reaumur to Degree Centigrade, divide your °Re figure by 0.8.

Example : convert 25 °Re to °C:

25 °Re = 25 ÷ 0.8 °C = °C
