"Most physicists do not recognize temperature, Θ, as a fundamental dimension of physical quantity since it essentially expresses the energy per particle per degree of freedom, which can be expressed in terms of energy (or mass, length, and time). Still others do not recognize electric charge, Q, as a separate fundamental dimension of physical quantity, since it has been expressed in terms of mass, length, and time in unit systems such as the cgs system." (http://en.wikipedia.org/wiki/Dimensional_analysis#Definition)

Since the number of particles and the degree of freedom are dimensionless, it seems to imply that temperature has the same dimension as energy, namely, [itex] M\ L^2\ T^{-2} [/itex]. However, I could not find any source for how temperature and charge can be expressed in terms of M, L and T. What are the correct expressions and how are they derived?
