Abstract
THE value of the “mechanical equivalent,” when deduced from experiments based on the direct transformation of mechanical work into heat, affords the best standard by means oof which to test the validity of our system of electrical units. It is evident, however, that the value of this test depends upon the accuracy of the “equivalent” determinations. The engineer may (very rightly) regard extreme numerical accuracy in this case as comparatively unnecessary, but from the physicist's point of view there are few natural constants whose exact determination is of equal importance.1
