$\textit{Gyromagnetic Ratio}$, also sometimes known as the magnetogyric ratio in other disciplines, of a particle or system is the ratio of its magnetic dipole moment to its angular momentum, and it is often denoted by the symbol, $\gamma$. Its SI coherent unit is the radian per second per tesla ($\mathrm{rad} \cdot \mathrm{s}^{-1} \cdot \mathrm{T}^{-1}$); because the radian is dimensionless this is equal to the coulomb per kilogram ($\mathrm{C} \cdot \mathrm{kg}^{-1}$).
$\mu = \gamma J$, where $\mu$ is the magnetic dipole moment, and $J$ is the total angular momentum.
