Understanding the Units

What is a Millicoulomb?

The coulomb is the SI derived unit of electric charge, equal to the charge transported by one ampere in one second (1 C = 1 A·s).

Named after Charles-Augustin de Coulomb (1736–1806), French physicist who quantified the electric force law.

Common contexts: electrostatics, chemistry.

What is an Ampere Hour?

An ampere-hour equals exactly 3,600 coulombs — a current of one ampere flowing for one hour. It is the standard battery-capacity rating.

Common contexts: battery capacity, power tools, EV.
