Newtonian constant of gravitation
(G)

Newtonian constant of gravitationhas symbol Ghas source: Jerrard, H.G., McNeill, D.B. 1992 Dictionary of Scientific Units, Chapman and Hall, 2001-09-27 09:33:00.0
has value 6.673 × 10-11 m3 kg-1 s-2has URL: http://physics.nist.gov/cgi-bin/cuu/Value?bg, 2001-09-27 09:33:00.0
has effect on other constants none, increases in the accuracy of its measurement have made no difference to the values of the other physical constants.has source: Jerrard, H.G., McNeill, D.B. 1992 Dictionary of Scientific Units, Chapman and Hall, 2001-09-27 09:33:00.0
has relationship no direct connection has, as yet, been established between G and any other physical quantities2001-09-27 09:33:00.0
has equation F = G × m1 × m2/r2, where F is the gravitational force of attraction, m1 and m2 are the masses for two bodies separated by r.has source: Jerrard, H.G., McNeill, D.B. 1992 Dictionary of Scientific Units, Chapman and Hall, 2001-09-27 09:33:00.0
