Is G a conversion factor or a fundamental unit?
G. Fiorentini, L. Okun, M. Vysotsky
Abstract
By using fundamental units c, h, G as conversion factors one can easily transform the dimensions of all observables. In particular one can make them all ``geometrical'', or dimensionless. However this has no impact on the fact that there are three fundamental units, G being one of them. Only experiment can tell us whether G is basically fundamental.
