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