are you there? do you mean that as in the actual value, or just some rough idea?

do you mean the center

anonymous · Answer

http://en.wikipedia.org/wiki/Cavendish_experiment or $$mg = mMG/r^2$$ M = mass of the earth ; r = radius of the earth - you can look these values up and calculate G

Just FYI, recent theoretical work would indicate that G is not so universally constant after all and varies within our Universe.

 ..hmm; id say by falling down alot and recording the data might be a start :)

anonymous · Answer

By going to a nearby inner-city and screaming "WHERE DA BIG G'S AT?!"

anonymous · Answer

You can use the formula g=GMm/r^2
So G=gr^2/Mm
