The Newtonian constant of gravitation denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies. It usually appears in Sir Isaac Newton's law of universal gravitation, and in Albert Einstein's theory of general relativity. The constant is expressed in SI units, meters cubed per kilogram per second squared.

Note: `(N * m^2)/(kg^2)" or " N(m/(kg))^2" or " m^3/(kg* s^2)` are all appropriate units for this constant.

Notes

the value for this equation is:       `6.67384*10^-11 (N * m^2)/(kg^2)"`
