Also Plancks constant is not an energy (as you would discover by finding out what the ”J” in Js means).

As I've said very many times in the last few days, the unit Js also gives a hint, what ##\hbar## might indicate. It's a fundamental constant of nature and thus provides a natural measure for some quantity with the unit Js, and that's the same as the unit length times momentum. In turn this indicates that it's the natural measure for phase space volumes, and this turns indeed out to be correct when you consider statistical physics of a many-body system.

ThePlanck constant, orPlanck's constant, is the quantum of electromagnetic action that relates a photon's energy to its frequency.

That's the physical problem that originally motivated Planck to come up with his constant, but its physical applications are not limited to that.

The Planck constant multiplied by a photon's frequency is equal to a photon's energy. The Planck constant is a fundamental physical constant denoted as {\displaystyle h}, and of fundamental importance in quantum mechanics. In metrology it is used to define the kilogram in SI units.[2]

Do you have a question about any of these things?

J = Joule

s = second

J . s = Joule . second

s = second

J . s = Joule . second
