A method is presented for obtaining a consistent set of thermodynamic parameters and temperature‐dependent thermodynamic variables for a real superconductor. The method depends upon determining a temperature‐dependent effective interaction strength for the particular material. Conversely, given the effective interaction strength for the superconductor, the thermodynamic variables as functions of temperature can be obtained. The method is illustrated for Al, V, Ta, Nb, and Pb. The results of this approach and the McMillan theory of the critical temperature are compared for Nb, Pb, and the In‐Tl alloy system.
