# Statampere

From Citizendium

In physics, the **statampere** (symbol **statA**) is the unit of electric current in both the cgs-esu (centimeter-gram-second electrostatic) system and the Gaussian system of units.

One statampere is defined as the flow of charge equal to 1 statcoulomb per second,

- 1 statA = 1 statC/s = C/(10⋅
*c*⋅s) = A/(10⋅*c*),

where *c* is the speed of light in m/s (*c* ≈ 3⋅10^{8} m/s) and A (ampere) is the SI unit of electric current; in SI units: 1 A = 1 C/s (coulomb per second).
