Expert Answer:

Generally  weight of an object is the  the force of gravity of earth on it, which we measure by spring or other balance.

But when we try to say so about earth, whose force of gravity do we refer? and how do we measure it?

It might be sun, moon, other planets.

So instead the same thing is talked as force of gravitation between sun and earth, or earth and moon and so on.

So as such weight of earth has some vague meaning.
