gravitational constant(G) is a constant everywhere ...
.its value is fixed but accletation due to gravity is different at different places....
actually g is gravitational field and its value is 9.8m/s^2 near the surface of earth....as we move away from the earth gravitational field changes so the value of g also changes.....
g(gravitational field or acc due to gravity))=GM/r^2
units are also diff as unit of g is m/s^2 and uint of G is Nm^2/kg^2
