About these units

Rankine: The degree Rankine (°R) is an absolute temperature scale using Fahrenheit-sized increments.

Kelvin: The kelvin (K) is the SI base unit of thermodynamic temperature. Since the 2019 SI redefinition, it is defined by fixing the Boltzmann constant at exactly 1.380 649 × 10⁻²³ J/K. Named aft...
