What is the relationship between Planck's constant and the energy of fermions (matter constituents) at rest?

i did write something then realised it was hideously wrong because you asked for rest energy :P

$$E = \hbar \omega$$ where $$\omega = \frac{1}{\hbar} \sqrt{0^2 c^2+ m^2 c^4}$$, no?

Planck's constant is merely a conversion factor, http://arxiv.org/abs/hep-th/0208093" [Broken].
