A proton's gyromagnetic ratio, `gamma_p`, also known as the magnetogyric ratio is 2.675222005E8 1/(s·T).
This constant represents the ratio of the electron's magnetic dipole moment to its angular momentum. The proton gyromagnetic ratio is reported in SI units of ``/(s*T)` or `C/kg`.
This constant is specified with a standard uncertainty (standard deviation) of: 0.000 000 063 E8 1/(s*T)
