Convert length/length/kelvin to length/length/degree réaumur

Vice Versa: length/length/degree réaumur to length/length/kelvin

Length/Length/Kelvin

The inverse kelvin (1/K) is the SI unit of the coefficient of linear thermal expansion. It expresses the fractional change in length of a material per degree kelvin change in temperature. Most metals have coefficients in the range of 10⁻⁵ to 10⁻⁶ per kelvin.

Length/Length/Degree Réaumur

The inverse degree Réaumur (1/°r) is a historical unit of thermal expansion coefficient based on the Réaumur temperature scale. Since 1°r equals 1.25 K, a coefficient in 1/°r is 0.8 times the value in 1/K. It is encountered in historical European scientific literature.
