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