Kilowatt-hours to milliamp-hours
Type a value in kWh to get it in mAh instantly.
That's 83× as big as an electric car battery — nothing on our list beats it. That is about 333,300 full phone charges.

What it means
How much energy is that?
Airlines limit spare batteries to 100 Wh without approval, which is why the Wh figure matters.
The math
How to convert kWh to mAh
Charge becomes energy only once you know the voltage: Wh = mAh × V ÷ 1000. The figures below use the voltage selected above.
Example: 5,000 kWh = 1.351×10⁹ mAh.
The table below assumes Phone cell (3.7 V). Change the voltage above and every number updates.
