The centimetre–gram–second system of units (CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways in which the CGS ...
Gaussian units constitute a metric system of physical units. This system is the most common of the several electromagnetic unit systems based on cgs (centimetre–gram–second) units. It is also called the Gaussian unit system, Gaussian-cgs units, or often just cgs units. [a] The term "cgs units" is ambiguous and therefore to be avoided if ...
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx /cm 2 or g / Bi /s 2, while the oersted is the unit of H -field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted. The units for magnetic flux Φ, which is the integral of magnetic B ...
The poise (symbol P; / pɔɪz, pwɑːz /) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS). [1] It is named after Jean Léonard Marie Poiseuille (see Hagen–Poiseuille equation). The centipoise (1 cP = 0.01 P) is more commonly used than the poise itself. Dynamic viscosity has ...
In some engineering fields, like computer-aided design, millimetre–gram–second (mmgs) is also used. [3] The current international standard for the metric system is the International System of Units (Système international d'unités or SI). It is a system in which all units can be expressed in terms of seven units.
The statcoulomb (statC), franklin (Fr), or electrostatic unit of charge (esu) is the unit of measurement for electrical charge used in the centimetre–gram–second electrostatic units variant (CGS-ESU) and Gaussian systems of units. It is a derived unit given by. 1 statC = 1 dyn 1/2 ⋅cm = 1 cm 3/2 ⋅g 1/2 ⋅s −1. That is, it is defined ...
The centimetre–gram–second system of units (CGS) is based on three base units: centimetre, gram and second. Its subsystems (CGS-ESU, CGS-EMU and CGS-Gaussian) have different defining equations for their systems of quantities for defining electromagnetic quantities and hence the associated units, with CGS-Gaussian units being selected from each of the other two subsystems.
An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram". [3] One dyne is equal to 10 micronewtons, 10 −5 N or to 10 nsn (nanosthenes) in the old metre–tonne–second system of units. 1 dyn = 1 g⋅cm/s 2 = 10 −5 kg⋅m/s 2 = 10 ...
