How do you convert vibrating silicon atom frequencies to energy in meV?

When considering a vibrating silicon atom.
I'm just not sure how to do the conversion

MeV is mega-electron volts which is equivalent to Joules or energy. So you can't convert frequency to energy.

I know, not directly, but I'm looking for a relation that's something along the lines of E=\hbar\omega but I don't know of any.

Essentially, I'm going from a unitless/normalized frequency of 2 to 80 mevs using \omega=2\sqrt{K_i/M} where K_i is 10.6 eV/\AA^2 and M is the mass of silicon. I should get approximately 80 mevs.. Not sure how I get there. I got to 1/s easily by using the mass of silicon in mevs/c^2 but that's about it
