Boltzmann factor units
WebThe SI unit of the Boltzmann constant is J/K and its value is 1.380649×10 −23. As the constant is used for microscopic constraints, the energy is expressed in terms of eV and thus the unit becomes eV/K. The value in this unit is 8.617333262×10 −5. It can also be expressed in the CGS unit which is erg/K.
