G (thing)

The universal constant of Gravitation,

G ~= 6.670 x 10^-11 n^.m²/kg²

or

G ~= 1.477 x 10^-10 lb-force^.ft²/lb-mass²

Applying G to the gravitational force formula

F = G m M / d²,

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.

(I think ME123 means N/kg and not simply N).
