Length per Length per Degree Rankine
°R⁻¹
Definition
The length per length per degree Rankine (°R⁻¹) is a unit of thermal expansion coefficient equal to 1.8 per kelvin. It represents the fractional change in length per unit temperature change in the Rankine scale, providing an absolute temperature-based measure for thermal expansion calculations.
History/Origin
Developed as part of the Rankine absolute temperature scale system, this unit provides thermal expansion measurements in absolute temperature units. It maintains the same relationship as the Fahrenheit unit but is used in contexts requiring absolute temperature measurements.
Current Use
Used in specialized engineering applications, particularly in thermodynamics and heat transfer calculations where absolute temperature measurements are required. It is commonly found in power generation, refrigeration, and aerospace engineering applications.

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.
