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⋅108 m/s) and A (ampere) is the SI unit of electric current; in SI units: 1 A = 1 C/s (coulomb per second).
