Degree Reaumur

°r

Definition

The degree Reaumur (°r) is a temperature interval unit equal to 5/4 of a kelvin. It was historically used in some European countries and provides a different scale for temperature differences, with one degree Reaumur representing a larger temperature change than one degree Celsius.

History/Origin

Named after René Antoine Ferchault de Réaumur, the degree Reaumur was developed in the 18th century as an alternative temperature scale. It was defined as 1/80 of the temperature difference between the freezing and boiling points of water, making it larger than the Celsius scale.

Current Use

Rarely used in modern applications but occasionally found in historical literature and some specialized scientific contexts. It is mainly of historical interest and is sometimes used in temperature interval calculations for historical data analysis.

Kelvin

Definition

The kelvin (K) is the SI base unit of thermodynamic temperature and is also used for temperature intervals. When measuring temperature differences, one kelvin equals one degree Celsius, making it the standard unit for temperature interval measurements in scientific and engineering applications.

History/Origin

Named after Lord Kelvin (William Thomson), the kelvin was established as the SI base unit for temperature in 1967. It was designed to provide an absolute temperature scale where zero represents absolute zero, and temperature intervals are measured in the same units as the temperature scale itself.

Current Use

Widely used in scientific research, engineering, and industrial applications for measuring temperature differences and intervals. It is the standard unit for temperature interval measurements in thermodynamics, heat transfer analysis, and temperature control systems.
