How to Convert Milliampere-Hours to Ampere-Hours
To convert from milliampere-hours (mAh) to ampere-hours (Ah), you divide the capacity in milliampere-hours by 1,000. For more information about milliampere-hours as a unit of measurement, visit our milliamperes-hour page.
Formula
Ampere-Hours = Milliampere-Hours / 1,000
or
Ah = mAh / 1,000
Examples
- 1 mAh = 1 / 1,000 = 0.001 Ah
- 10 mAh = 10 / 1,000 = 0.01 Ah
- 100 mAh = 100 / 1,000 = 0.1 Ah
- 1,000 mAh = 1,000 / 1,000 = 1 Ah
