"WebGiven a thermodynamic system at an absolute temperature T, the average thermal energy carried by each microscopic degree of freedom in the system is 1 2 kT (i.e., about 2.07 × 10−21 J, or 0.013 eV, at room temperature). This is generally true only for classical systems with a large number of particles, and in which quantum effects are negligible. " - Kinetic energy formula in thermodynamics
