How to Convert Milliampere-Hours to Coulombs
To convert from milliampere-hours (mAh) to coulombs (C), you multiply the capacity in milliampere-hours by 3.6. For more information about milliampere-hours as a unit of measurement, visit our milliamperes-hour page.
Formula
Coulombs = Milliampere-Hours × 3.6
or
C = mAh × 3.6
Examples
- 1 mAh = 1 × 3.6 = 3.6 C
- 10 mAh = 10 × 3.6 = 36 C
- 100 mAh = 100 × 3.6 = 360 C
- 1,000 mAh = 1,000 × 3.6 = 3,600 C
When to Convert Milliampere-Hours to Coulombs
This conversion is useful in electrical engineering and battery technology, as milliampere-hours are commonly used to express the capacity of smaller batteries.
Portable Electronics
