The Boltzmann constant (k or kB) is a physical constant relating energy at the individual particle level with temperature, which must necessarily be observed at the collective or bulk level. It is the gas constant R divided by the Avogadro constant NA:
It has the same dimension (energy divided by temperature) as entropy. It is named after the Austrian physicist Ludwig Boltzmann.

Famous quotes containing the word constant:
“In verse one can take any damn constant one likes, one can alliterate, or assone, or rhyme, or quant, or smack, only one MUST leave the other elements irregular.”
—Ezra Pound (1885–1972)
