    it's derived from empirical evidence when the linear and proportional relationship between the energy in electromagnetic radiation and frequency was measured - with the proportionality constant equal to 6.626*10^-34 Js http://physics.info/planck/

    The first value for constant h, were obtained by the same M. Planck, using the available experimental data. The value obtained by M. Planck, in the far 1901, was: \[\Large h = 6.55 \times {10^{ - 27}}erg \cdot \sec \] here is the source: \[\large \begin{gathered} {\text{M}}{\text{. Planck}}{\text{, Annalen der Physik (Lipsia) }}{\mathbf{4}}{\text{, 564 }}\left( {{\text{1901}}} \right); \hfill \\ Abhandlungen,{\text{ Vol}}{\text{. 1}}{\text{, pag}}{\text{. 728}}{\text{.}} \hfill \\ \end{gathered} \]

    This one is detailed derivation of plank's constant. https://www.youtube.com/watch?v=syQbWP-7WC4
