Dear Baba

Gravitational Constant (G)=

6.67300 × 10-11 m3 kg-1 s-2

while acceleration due to gravity (g) =9.80665 m/s2

Both diiffer in units and dimension also.

All the best

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
