Popis: We have measured Newton's gravitational constant with a commercially available mass comparator. In this experiment, the difference of the gravitational force of 13,600 kg mercury on two 1.1 kg copper masses was measured with a relative statistical uncertainty of 16.3times10-6. Including the systematic uncertainties we determine the gravitational constant G to be 6.674 252(122)times10-11 m3kg-1s-2.
