# Ampere meaning

The accepted standard unit used for measuring how fast an electric current flows is an example of an ampere.

^{18}electrons per second.

^{−7}newtons per meter of length. The value of an ampere in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units.

^{-7}newton per meter of length: abbrev.

*A*or

*amp.*

^{18}) electrons passing by the point of measurement in one second. See ampere-hour, volt and watt.

**1**.The unit of electric current equivalent to the flow of one coulomb of charge per second past any cross section at any point in a circuit, with a coulomb being 6.24

Definition: The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2 x 10–7 newton per metre of length. (The International Bureau of Weights and Measures)
