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...
Fahrenheit: The degree Fahrenheit (°F) is a temperature unit in the US customary system. On this scale, the freezing point of water is 32 °F and the boiling point is 212 °F — exactly 180 degrees apart. ...
