Abstract
We present the results of a measurement of G made with a torsion-strip bala nce used in two substantially independent ways. The two results agree to wi thin their respective uncertainties; the correlation coefficient of the two methods is -0.18. The result is G = 6.675 59(27) X 10(-11) m(3) kg(-1) s(- 2) with a standard uncertainty of 4.1 parts in 10(5). Our result is 2 parts in 10(4) higher than the recent result of Gundlach and Merkowitz.
