The Attempt at a Solution

Seems pretty strightforward:
\hbar c = Gm^2

multiply both sides by c^4

\hbar c^5 = Gm^2c^4

knowing that m^2c^4 is E^2=(\hbar \omega)^2 then

\hbar c^5 = G\hbar^2 \omega^2

dividing \hbar^2 off both sides

\frac{c^5}{\hbar}=G\omega^2

then this is the same as

\frac{c^5}{\hbar}=G\frac{k}{m}

because \omega^2 = \frac{k}{m} so multiplying m on both sides gives

\frac{c^5}{\hbar}m=Gk

Then finally multiplying \hbar on both sides gives you

\frac{c^5}{\hbar}m \hbar=Gk\hbar

Has there been anything wrong in this so far?

Basically it was suggested I had my dimensions wrong, but the derivation is so simple, I couldn't see anything wrong with. My question was simple enough I think.. is there anything wrong with it? Either it is wrong and I am doing this with the wrong dimensions, or it is right and there was no problem to begin with..

which is it, please answer!

What does this derivation do ? What's it good for ?

I haven't fully decided on this. There are two main features from the final equation written here in the OP.

\frac{c^5}{\hbar}M\hbar = G(k\hbar)

which in another form is simply

\frac{c^5}{\hbar}S = G(k\hbar)

This equation has the features that the left handside is in fact just a rescalling of the spin S and the right handside has the feature of momentum of any quanta given as (\hbar k). So for a specific wave equation, the right hand side may have an implication for

\psi(x,t) = Aexp(ikx - i \hbar k2t / 2m)

because this has a definite momentum, p = ħk. But because this has the form of spin on the left handside, it can be futher written as

\frac{c^5}{\hbar} \frac{\hbar}{2} \sigma_i = G(\hbar k)

Here \sigma_i is the Pauli Spin Matrices, where the subscript represents any of the three dimensions of space \sigma_i = (\sigma_x, \sigma_y, \sigma_z) and of course, if you use all three dimensions, this directly effects the momentum component to make (\vec{\hbar k}).

Of course, I have thought about other applications.
