What is the value of G in force of an gravity

The product of the masses of two objects must be multiplied by G, divided by the square of their separation, and used to determine their gravitational attraction to one another. The equation is $F=G{m}_1{m}_2/r^2$.
$G=6.67\times {10}^{-11}{m}^{3}k{g}^{-1}{s}^{-2}.$
G is universal gravitational constant
acceleration of gravity ,$g=9.8m/s^2$
