The Newtonian constant of gravitation, about 6.674×10−11 m3kg−1s−26.674\times 10^{-11}\,\mathrm{m}^3\mathrm{kg}^{-1}\mathrm{s}^{-2}6.674×10−11m3kg−1s−2.
Sets the overall strength of Newtonian gravity. It is the same for every pair of masses.
Changing GGG would scale every gravitational force in the universe by the same factor.
