quantum mechanics - Can someone explain Planck's constant simply?



Can someone explain Planck's constant simply?


I know the math, however I don't understand the relevance.


To explain what I'm asking, what is the significance of it when doing quantum mechanical calculations such as getting Planck length or other such equations.



Answer



Others will probably answer much more complex versions, and they will explain much better. But here is a very simple answer:


Its numerical value is the energy of a single photon with the frequency of $1 Hz$.
