How to convert mAh to Ah

mAh to Ah calculation formula

Q_(Ah) = Q_(mAh) / 1000

The electric charge Q in amp-hours (Ah) is equal to the electric charge Q in milliamp-hours (mAh), divided by 1000.

So,

Ah = mAh / 1000
amp-hour = milliamp-hour / 1000

For example:

Electric charge (Q_(mAh)) = 500mAh

Electric charge (Q_(Ah)) = 500mAh / 1000 = 0,5Ah
