Key Terminology

Degree Réaumur [°r]
A temperature interval unit equal to 1/80 of the difference between water's freezing and boiling points, where 1 °r equals 1.25 °C.
Degree Celsius [°C]
A unit measuring temperature intervals equal in magnitude to one kelvin, commonly used for expressing temperature differences.
