The statampere (abbreviated statA or A-esu) is the unit of electric current in the cgs (centimeter/gram/second) system of electrostatic units (esu). It is the equivalent of one statcoulomb (1 statC), also called one electrostatic unit (1 esu), of charge carriers moving past a specific point in one second.

The statampere is a small unit of current, equivalent to approximately 3.3356 x 10 ^-10 ampere (A) or 0.33356 nanoampere (nA). In most applications, the ampere, which is the unit of current in the International System of Units ( SI ), is preferred.
