Universal law of gravitation: Every particle of matter in the universe attracts every other particle with a force which varies directly as the product of the masses of the two particles and inversely as the square of the distance between them.
i.e., F α m1 x m2
F α (1/r²)
Combining both the factors,
F α (m1 x m2) / r²
F = G (m1 x m2) / r², where m1 & m2 are the masses of the particles, r, the distance between them and 'G' is a constant of proportionality known as "Gravitational Constant". It has the same value everywhere in the universe.
In cgs system,
the value of "G" is 6.67 x 10^-8 dyne cm² gm^-2
In the SI system,
the value of "G" is 6.67 x 10^-11 newton m² kg^-2
If m1 = m2 = 1 unit and r = 1 unit, then F = G

G = 6.673 x 10^ - 11 m^3/kg s^2
That crazy unit reads as metres cubed per kilograms seconds squared.

hi there,
if you go to
"www.16pi2.com/gravitational_constant.htm
you will find it,
or yahoo search "gravitational constant" and it will come up with all the information that you will need.
good luck

Wiki, help!
http://en.wikipedia.org/wiki/Gravitational_constant
If you were just looking for the value, the inside cover of any elementary physics book will have it. It's abbreviated by capital G.
