Thus, for example, the CGS unit of pressure, barye, is related to the CGS base units of length, mass, and time in the same way as the SI unit of pressure, pascal, is related to the SI base units of length, mass, and time: 1 unit of pressure = 1 unit of force / (1 unit of length) 2 = 1 unit of mass / (1 unit of length × (1 unit of time) 2)
Gaussian units constitute a metric system of units of measurement. This system is the most common of the several electromagnetic unit systems based on the centimetre–gram–second system of units (CGS). It is also called the Gaussian unit system, Gaussian-cgs units, or often just cgs units.

In cgs units, if the mass is in grams and the velocity in centimeters per second, then the momentum is in gram centimeters per second (g⋅cm/s). Being a vector, momentum has magnitude and direction. For example, a 1 kg model airplane, traveling due north at 1 m/s in straight and level flight, has a momentum of 1 kg⋅m/s due north measured ...
[note 2] Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10 −10 statcoulomb [note 3] (generally called e.s.u. (electrostatic unit) in older scientific literature), which were separated by 1 ångström. [note 4] This gave a convenient unit for molecular dipole moments.
In solid-state physics, crystal momentum or quasimomentum is a momentum-like vector associated with electrons in a ... called electron ... (in cgs units): [3]: ...
In the atomic world the angular momentum of a particle is an integer (or half-integer in the case of fermions) multiple of the reduced Planck constant ħ. This is the basis for defining the magnetic moment units of Bohr magneton (assuming charge-to-mass ratio of the electron) and nuclear magneton (assuming charge-to-mass ratio of the proton).
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.
