ampere (A)
The basic unit of electric current in the meter-kilogram-second system; equivalent to one coulomb per second.

One ampere is the current that, if held constant in two parallel conductors of infinite length at a distance of one meter apart in a vacuum, will produce a force of 2 X 10 newton per meter of length.

André Marie Ampère (1775-1836) was a French physicist and mathematician, a key figure in the development of the fields of electricity and magnetism.

Ampère produced a definition of the unit of measurement of current flow, now known as the ampere.
