About Per Degree Réaumur (1/°Ré)
Thermal expansion coefficient per degree Réaumur. Since 1 °Ré interval = 1.25 K, 1/(1.25 K) = 0.8 K⁻¹.
History: Historical unit from 18th- and 19th-century French and European physical chemistry.
Common Uses: Historical metallurgy and physics literature translation.
About Per Kelvin (1/K)
The SI unit for linear and volumetric thermal expansion coefficients, defined as fractional dimension change per kelvin temperature change.
History: Adopted in SI thermodynamics to express material strain response to temperature differentials.
Common Uses: Materials science, structural engineering, precision optical mounting, thermal stress analysis.
❓ Frequently Asked Questions
How many Per Kelvins are in 1 Per Degree Réaumur?
There are exactly 0.8 Per Kelvins in 1 Per Degree Réaumur (1 1/°Ré = 0.8 1/K).
What is the formula to convert Per Degree Réaumur to Per Kelvin?
