Type a value in mAh to get it in C instantly.
3,600C
That's 240× as much charge as a lightning strike, while a phone battery is 5× more. That is about 2.247×10²² electrons.
Convert the other way: C to mAh
What it means
How much charge is that?
Charge is not energy: to get watt-hours from mAh you also need the voltage.
The math
How to convert mAh to C
To convert milliamp-hours to coulombs, multiply by 3.6.
Example: 1,000 mAh × 3.6 = 3,600 C.
In the other direction, 1 C = 0.277778 mAh.
