Abstract

For the past several years, we have been using the torsion balance developed at the Bureau International des Poids et Mesures (BIPM) to measure the gravitational constant $G$. The most notable feature of the apparatus is that it allows the measurement of $G$ with two different methods: the Cavendish method and the Servo method. The systematic effects are different in several important variables, leading to an improved combined result. In the past year, we have identified a gas pressure effect that hampered previous measurements at the National Institute of Standards and Technology
