The proton gyromagnetic ratio in water has been measured by the low field method using atomic magnetic resonance in 4He, a multicurrent solenoid and an induction method for the dimensional measurement of the solenoid. The result for air and vacuum environment is γ'p (low, air)=2.67515451×108 s-1 T-1 (0.18×10-6), γ'p (low, vacuum)=2.67515418×108 s-1 T-1 (0.18×10-6), based on the adopted values KJ-90=483597.9 GHz/V, RK-90=25812.807 Ω, and measured values γ(4 He)/γ'p=658.200556, γ(4He) (air)=1760.78819×108 s-1 T-1 (0.18×10-6), KJ-90, RK-90
