You yourself knew the answer? Why did you ask the question then?

Gravity is not a dimension. It is a fundamental force which is weakest among all the force. As per standard theory--- gravity is weak because of increasing expanding velocity or recessional velocity as per hubble's law--

Newton's Universal Law of Gravitation has the mathematical form:
F = G (m1)(m2)/r^2
So, G = F r^2/(m1×m2)
So, [G] = ([Force]×[Distance]^2)÷([Mass]^2)
So, [G] = ( [M L T^(-2) ] × [L^2] )÷ [M^2]
So, [G] = [ M^(-1) L^3 T^(-2) ]
F = G (m1)(m2)/r^2
So, G = F r^2/(m1×m2)
So, [G] = ([Force]×[Distance]^2)÷([Mass]^2)
So, [G] = ( [M L T^(-2) ] × [L^2] )÷ [M^2]
So, [G] = [ M^(-1) L^3 T^(-2) ]
