6.242×10²¹e
That's 67× as much charge as a lightning strike, while a phone battery is 18× more. That is about 6.242×10²¹ electrons.
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 C to e
To convert coulombs to elementary charges, multiply by 6.242×10¹⁸.
Example: 1,000 C × 6.242×10¹⁸ = 6.242×10²¹ e.
In the other direction, 1 e = 1.602×10⁻¹⁹ C.
