How to convert electric charge of milliamp-hour (mAh) to amp-hour (Ah).
The electric charge Q(Ah) in ampere-hours is equal to the electric charge Q(mAh) in milliamp-hour divided by 1000:
Q(Ah) = Q(mAh) / 1000
So amp-hour is equal to milliamp-hour divided by 1000:
ampere-hours = milliampere-hours / 1000
or
Ah = mAh / 1000
Convert current of 300 milliampere-hour to ampere-hour?
The electric charge Q is equal to 300 milliamp-hour divided by 1000:
Q = 300mAh / 1000 = 0.3Ah
