Milliampere-hours (mAh) and ampere-hours (Ah) are units used to measure the capacity of a battery or the amount of charge a battery can store and deliver.
Milliampere-hours (mAh)
Milliampere-hours are a smaller unit of charge commonly used for smaller electronic devices such as smartphones, tablets, and small electronics. 1 milliampere-hour is equal to one-thousandth of an ampere-hour (0.001 Ah). It indicates the amount of current a battery can deliver over the course of one hour, with a milliampere (mA) being one-thousandth of an ampere (A).
Ampere-hours (Ah)
Ampere-hours are used for larger devices and applications like electric vehicles, renewable energy storage systems, and industrial equipment. 1 ampere-hour represents the flow of one ampere of current for one hour. It’s a measure of the total charge capacity of a battery.
How to convert milliampere-hours to ampere-hours
1mAh = 0.001Ah
or
1Ah = 1000mAh
Milliampere-hours to ampere-hours conversion formula
Q(Ah) = Q(mAh) / 1000
Example – Convert 3 milliampere-hours to ampere-hours:
Ans. Q(Ah) = 3mAh / 1000 = 0.003Ah
