S = k ln W and S = k ln Omega

With S = k ln W
W = V^N
V = volume
N=number of particles
This expression is for entropy in non uniform distribution non equilibrium systems.

S = k ln Omega
This statistical mechanics expression for entropy denotes uniform probibility
distribution for equilibrium (max entropy) systems. Omega = 1.2.3 ...
So is there any quantitative difference between W and Omega ?

Check out the value of the constant "k" in each case.
I think that the two different definitions of "k" will illuminate the differences between the two equations.
