Definition

  • $\ extit{Ampere Hour}$ 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 ($3.6 \\,coulombs$).
