A constant which describes the relationship between temperature and kinetic energy for molecules in an ideal gas.
Equal to the ideal gas law constant divided by Avogadro′s number.
k = 1.38062x10-23 JK-1
k = 8.617342 × 10-5 eV K-1
k = 2.0836644 × 1010 Hz K-1
The value was defined by the 19th century Austrian physicist, Ludwig Boltzmann
