# ampere (A)

Ampere (A) is named after the French physicist André Marie Ampère (1775-1836). According to the International System of Units(SI), the ampere is the unit for electric current.

br> One ampere is defined as the current that produces a force of 2^-7 newtons per meter of length between two parallel wires of infinite length located one meter apart in free space.

Another definition of the international system of units specifies that 1 coulomb per second is equal to 0.999835 amperes.

The ampere (A) is prefixed as kilo amps (kA), equivalent to 10^3, milli amps (mA), 10^-3, micro amps (µA), 10^-6, nano amps (nA), 10^-9, and pico amps (pA), 10^-12.
