Thanks daddy

I just got confused since it was called 'Gravitational Constant' but it appears it is relative to the place where you measure the force.of gravity

The force is proportional to the product of the masses and an inverse square of the distance. Mass squared per distance squared isn't a unit of force, so you multiply by big G to put it in the correct units. It's a unit conversion.

g =/= G

no, G is always the same. g depends on local mass distribution though

Big G is always he same (unless you change units). Small g is the acceleration due to gravity, which changes.

Like this:

F = m*g = (m*M*r^-2) * G

Different r, M, or m will give you a different g. When people refer to g, though, they almost certainly are talking about the value computed at the earths surface which is about 9.8 m/s/s
