Why ampere is a base unit?

Starting on May 20, 2019, the ampere is based on a fundamental physical constant: the elementary charge (e), which is the amount of electric charge in a single electron (negative) or proton (positive). The ampere is a measure of the amount of electric charge in motion per unit time ― that is, electric current.
