About these units

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...

Celsius: The degree Celsius (°C) is the SI-derived unit of temperature. It is defined so that 0 °C = 273.15 K exactly, with the same unit increment as the kelvin.
