m r c = ℏ' This formula demonstrates that by inputting the Planck mass and Planck length as the mass and radius, respectively, we derive what we term the "traditional" Planck constant ...

That’s pretty much all you need for instruments to determine Planck’s constant to a decent degree of precision, the way that [poblocki1982]’s did. There’s a little more to it, of course ...

The wavelength emitted is a function of the energy times a constant (h), now known as Planck's constant. Though Planck's idea was not immediately believed by most physicists, it is now accepted as ...
