# Why the capacity of batteries are measured in Ah (Ampere hour) and not A/h (Ampere per hour) ?

$1 A h = 1 A \cdot 1 h$.
An equation which uses current and time is $I \setminus \Delta t = \setminus \Delta Q$.
So, $1 A h$ represents $3 , 600 C$ or how much charge is needed to move 1 ampere of current around a circuit for 1 hour.
