# kinetic temperature

Kinetic temperature is the temperature of a gas defined in terms of the average kinetic energy of its atoms or molecules. It is given by:

*T* = 2/3 1/*k* avg(½ *mv *^{2})

where *T* is the kinetic temperature, *k* is Boltzmann's constant, *m* is the particle mass, and *v* is the particle velocity. In
thermal equilibrium, values of kinetic temperature correspond well with
those of other measures of temperature, such as effective temperature; otherwise,
they may bear little resemblance.
