How do you calculate g?

Newton’s law of universal gravitation states  Newton'sGravit

where: F is the force between the masses, G is the gravitational constant, M1 is the first mass, M2 is the second mass, and R is the distance between the centers of the masses.

The gravitational force at the planet’s surface is m2g

where: F is the gravitational force, M2 is the second mass, g is the acceleration of gravity.

Let’s consider M1 is the planet/star and M2 is the object on the surface of the planet/star.

Now, we could calculate g where we want at the Universe.
