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

To convert Length/Length/Degree Reaumur to Length/Length/Degree Celsius, multiply your 1/°R figure by 0.8.

Example : convert 25 1/°R to 1/°C:

25 1/°R = 25 × 0.8 1/°C = 1/°C

To convert Length/Length/Degree Celsius to Length/Length/Degree Reaumur, divide your 1/°C figure by 0.8.

Example : convert 25 1/°C to 1/°R:

25 1/°C = 25 ÷ 0.8 1/°R = 1/°R
