Although current is defined as the rate of flow of charge, i. e. I = Q/t = Ampere (unit), why is its unit Ampere included in the 7 fundamental units?

Explanation:

The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to 2×10−7 newtons per metre of length. That is why ampere is included in the seven fundamental units.
