Boltzmann constant: Difference between revisions

Revision as of 09:59, 22 June 2007

The Boltzmann constant ( $k$ or $k_{B}$ ) is the physical constant relating temperature to energy.

It is named after the Austrian physicist Ludwig Eduard Boltzmann. Its experimentally determined value (in SI units, 2002 CODATA value) is:

k_{B}=1.3806505(24)\times 10^{-23}

\left.JK^{-1}\right.

=8.617343(15)\times 10^{-5}

\left.eV\right.

\left.K^{-1}\right.
