Ampere Hour

\(\textbf{Ampere hour}\) is a practical unit of electric charge equal to the charge flowing in one hour through a conductor passing one ampere. An ampere-hour or amp-hour (symbol \(Ah,\,AHr,\, A \cdot h, A h\)) is a unit of electric charge, with sub-units milliampere-hour (\(mAh\)) and milliampere second (\(mAs\)). One ampere-hour is equal to 3600 coulombs (ampere-seconds), the electric charge transferred by a steady current of one ampere for one hour. The ampere-hour is frequently used in measurements of electrochemical systems such as electroplating and electrical batteries. The commonly seen milliampere-hour (\(mAh\) or \(mA \cdot h\)) is one-thousandth of an ampere-hour (\(3.6 \,coulombs\)).
