Boltzmann constant: Difference between revisions

Revision as of 14:45, 23 February 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 1 0^{- 23}

J K^{- 1}

= 8.617343 (15) \times 1 0^{- 5}

e V

K^{- 1}
