Is G a conversion factor or a fundamental unit?
PACS: 06.20.Fn, 06.20.Jr
Abstract
By using fundamental units c, \hbar, 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.
