Boltzmann constant

Description

The Boltzmann constant k has the SI unit [J·K^-1] (IUPAC), but more strictly the units for energy per particles per temperature is [J·x^-1·K^-1].

k = f·e^-1, the electrochemical constant f times the elementary charge e.

k = R·N_A^-1, the gas constant R divided by the Avogadro constant N_A.

Abbreviation: k [J·x^-1·K^-1]
