Abstract
Measurements of G, the Newtonian constant of gravitation, in laboratory experiments have a more than two hundred years' history. Although the accuracy of the best modern experimental measurements of G reaches 15-40 ppm, the scatter of the measured values is large enough, and the knowledge of the absolute value of G is still rather poor. The results of the G measurements which were used for CODATA adjustments, as well as the CODATA values, are reviewed in the paper.
