Gyromagnetic ratio

In physics, the gyromagnetic ratio (also sometimes known as the magnetogyric ratio^[1] in other disciplines) of a particle or system is the ratio of its magnetic moment to its angular momentum, and it is often denoted by the symbol $γ$ , gamma. Its SI unit is the radian per second per tesla (rad⋅s⁻¹⋅T⁻¹) or, equivalently, the coulomb per kilogram (C⋅kg⁻¹).^{[citation needed]}

The term "gyromagnetic ratio" is often used^[2] as a synonym for a different but closely related quantity, the $g$ -factor. The $g$ -factor only differs from the gyromagnetic ratio in being dimensionless.
