Convert ampere second to coulomb

Ampere-Second

The ampere-second (symbol: A·s) is equivalent to one coulomb, the SI unit of electric charge. It represents the charge transferred by a current of one ampere flowing for one second.

Coulomb

The coulomb (symbol: C) is the SI unit of electric charge. It is the charge transported by a constant current of one ampere in one second. One coulomb equals the charge of approximately 6.242×10¹⁸ elementary charges (electrons or protons).
