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
