Unit abA
Name abampere
Category Electric Current
Details An abampere (abA) is a unit of electric current used in the centimeter-gram-second (CGS) system of electromagnetic units, which is a subsystem of the CGS system of units. It is equivalent to 10 amperes in the International System of Units (SI).

The CGS system was developed in the 19th century as a way to simplify the measurement of physical quantities in scientific research. The abampere, specifically, was introduced as part of the electromagnetic (EM) subsystem within the CGS system to standardize the measurement of electric current in these units. However, the SI system of units has largely replaced the CGS system, including the abampere, in modern scientific work and is now the most commonly used system of units in the world.
