# Boltzmann Gas Constant (KB) Calculation

The calculator calculates the Boltzmann gas constant (KB) using gas constant and avagadaro constant.

 Gas constant (R): Avagadaro (NA): meter

 Boltzmann constant (k or kB) : radians/sec

Formula :

k = R / NA

Where,

k = Boltzmann constant,

R = Gas constant,

### Boltzmann Constant

The Boltzmann constant is a physical constant obtained by taking the ratio of two constants namely gas constant and Avogadro number, introduced by Max Plank and named after Ludwig Boltzmann and used in diverse disciplines of physics.

It is used to express Boltzmann factor.

In classical statistical mechanics, Boltzmann Constant is used to expressing the equipartition of the energy of an atom.

It plays a major role in the statistical definition of entropy.

In semiconductor physics, it is used to express thermal voltage.
