If, as Planck did, you observe that Energy of a photon is proportional to its frequency, then the dimensions of the constant numerical ratio between them are dictated by the dimensions of energy and frequency. Its very simple. 'h' is the result, its dimensions MUST BE such that the dimensional analysis is correct, and its numeric value dependant on the particular system of units you use.
