  The discrepancies between recently reported experimental values of the
gravitational constant were analysed within an inertia interpretation of MOND
theory. According to this scenario the relative gravitational acceleration
between a test mass and an array of source masses determines the magnitude of
post Newtonian corrections at small magnitudes of acceleration. The analysis
was applied to one of the most advanced recent Cavendish-type experiment which
revealed an experimental value for the gravitational constant of 180 ppm above
the current CODATA value with more than five standard deviations significance.
A remarkable agreement between this discrepancy and the acceleration anomalies
inherent of galaxy rotation curves was found by a consistent extrapolation
within the framework of MOND. This surprising result suggests that the two
anomalies on totally different length scales may originate from the same
underlying physics.
