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

    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.

    How do you find the Universe's gravitational Constant "G"? ..hmm; id say by falling down alot and recording the data might be a start :)

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

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