G is Newton's universal gravitational constant in the formula
F=GMm/r^2
Or
G = Fr^2 / Mm
Where M and m are two masses and r is the distance between the two masses.
The unit of G is N*m^2*kg^(-2).
If we consider a unit mass and calculate the force exerted on this unit mass by the mass M,
F / m = GM / r^2
If r is fixed then F/ m becomes a constant.
If we write F/m = g
g = G M / r^2.
Thus the relation between g and G is given by the above equation.
The unit of g is m/s^2.
G is a universal constant which is independent of M m and r,
where as g is a constant which depends upon M and r.
g is force per unit mass or acceleration. It has dimensions of 1in length and -2 in time and 0 in mass.
G has a dimension of 3 in length -1 in mass and -2 in time and has no special name for this quantity.
