Definition of enthalpy: \f$h= u + pv = u + p / \rho\f$.
Rearranging for internal energy yields: \f$u = h - pv\f$.
Exploiting the Ideal Gas assumption (\f$pv = R_{\textnormal{specific}} T\f$)gives: \f$u = h - R / M T \f$.
The universal gas constant can only be used in the case of molar formulations.
