The universal constant of Gravitation,

**G** ~= 6.670 x 10^{-11} n^{.}m^{2}/kg^{2}

or

**G** ~= 1.477 x 10^{-10} lb-force^{.}ft^{2}/lb-mass^{2}

Applying G to the gravitational force formula

F = G m M / d^{2},

where m is the mass of one body, M is the mass of the other body, and d is the distance between them, yields the force in pounds of force or newtons.
