In this study the Newton's gravity constant G has been measured at scale of atoms by the quantum resonance method other than Cavendish's torsion-balance way. The analyzed and experiment model is based on the "hyperfine splitting" of the ground energy state of hydrogen atom. The result is that only in empty space the G is constant, in hydrogen atom (near the distance of Bohr radius), the gravitational constant G=6.7192878(13)\times10-11 N\cdotm2/kg2; in vacuum, G=6.6722779(13)\times10-11 N\cdotm2/kg2. This method of experiment has eliminated all sources of possible experimental errors associated with the classical and existed setup, and with a precision more better than existing experiments.
