Length per Length per Degree Reaumur
°r⁻¹
Definition
The length per length per degree Reaumur (°r⁻¹) is a unit of thermal expansion coefficient equal to 0.8 per kelvin. It represents the fractional change in length per unit temperature change in the Reaumur scale, providing a historical measure for thermal expansion calculations.
History/Origin
Developed as part of the Reaumur temperature scale system, this unit was historically used in some European countries for thermal expansion measurements. It provides a different scale relationship compared to Celsius and Fahrenheit units, reflecting the unique characteristics of the Reaumur scale.
Current Use
Rarely used in modern applications but occasionally found in historical literature and specialized scientific contexts. It is mainly of historical interest and is sometimes used for temperature interval calculations involving historical data or legacy systems.

Length per Length per Kelvin
1/K
Definition
The length per length per kelvin (1/K) is the SI unit of thermal expansion coefficient, representing the fractional change in length per unit temperature change. It quantifies how much a material expands or contracts when subjected to temperature changes, making it essential for materials science and engineering applications.
History/Origin
Derived from the fundamental relationship between temperature and dimensional changes in materials, this unit became standardized with the adoption of the International System of Units. It provides a consistent measure for thermal expansion behavior across different materials and temperature scales.
Current Use
Widely used in materials science, mechanical engineering, and construction for designing components that experience temperature variations. It is essential for calculating thermal stresses, designing expansion joints, and predicting dimensional changes in structures and machinery.
