What exactly is an ampere hour?
An ampere hour combines the quantity of current with the time required to completely discharge a battery.
What is a coulomb ?
A coulomb (C) is the standard unit of electric charge in the International System of Units (SI). It is the amount of electricity that a 1-ampere (A) current carries in one second (s).
A quantity of 1 C is equal to the electrical charge of approximately 6.24 x 1018 electrons or protons.

Formula for converting ampere-hours to coulombs:
The charge expressed in coulombs is equal to the charge expressed in ampere-hours multiplied by 3600:
C = Ah × 3600
