Nobody invented it. The gravitational constant was there - long before the first human being walked on this planet.

The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.
Why g is called the universal gravitational constant.Answer:Because it's the constant in Newton's Law of Universal Gravitation.It's "gravitational" because it is related to gravity; "universal ... constant" because it is the same in all cases."Universal" because it applied to the whole of the Universe.Another answer. But, g isn't called the universal gravitational constant.g is the acceleration due to gravity on our planet only.= 9.81 m s-2The universal gravitational constant is G (often called big G ) = 6.673 x 1011 m3 kg-1 s-2.It appears in Newton's equation f= Gm1m2 / d2 .
They are [L^3]*M^-1][T^-2].
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
