Milliampere-hours to Coulombs Converter mAh → C
1 milliampere-hour (mAh) = 3.6 coulombs (C). Type a value below — the conversion happens instantly, entirely on your device.
1 mAh = 3.6 C
1 milliampere-hours = 3.6 coulombs
1 × 3.6 = 3.6
1 mAh equals 3.6 C, so multiplying by 3.6 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert milliampere-hours to coulombs
coulombs = milliampere-hours × 3.6 — multiply the milliampere-hour value by 3.6.
Example: 10 mAh = 36 C.
To convert the other way: milliampere-hours = coulombs ÷ 3.6 — or use the dedicated C to mAh converter .
