When mass of any elementary particle is extremely small/negligible compared to macroscopic bodies, highly curved microscopic space-time can be addressed with large gravitational constants and magnitude of elementary gravitational constant seems to increase with decreasing mass and increasing interaction range. In this context, in earlier publications, three large atomic gravitational constants have been defined pertaining to electroweak, strong and electromagnetic interactions. In a semi empirical way, in this paper, an attempt has been made to derive the earlier proposed relations connected with the four gravitational constants. This model is first of its kind with a simultaneous existence of four gravitational constants pertaining to the four basic physical interactions and can be called as 4G model of final unification.
