Frequently Asked Questions
-
What does length/length/degree Réaumur measure?
-
It measures the fractional change in length per degree Réaumur temperature change, used as a coefficient of linear thermal expansion.
-
How is length/length/degree Celsius related to per kelvin units?
-
Length/length/degree Celsius is numerically equivalent to per kelvin units because the sizes of Celsius and kelvin degrees are identical.
-
Why should I convert from Réaumur to Celsius for thermal expansion?
-
Converting to Celsius allows compatibility with modern engineering standards and materials data that use the Celsius or kelvin temperature scale.
Key Terminology
