## How to convert Wh to mAh

How to convert watt-hour (Wh) to milliampere-hour (mAh).

## Watt-hour to milliampere-hour calculation formula

The electric charge

Q_{(mAh)}in milliampere-hours (mAh) is equal to the energyE_{(Wh)}in watt-hours (Wh) times 1000 divided by the voltageV_{(V)}in volts (V):

Q_{(mAh)}=E_{(Wh)}×1000 /V_{(V)}So milliamp-hour is equal to watt-hour times 1000 divided by volts:

milliamp-hour = watt-hour × 1000 / V

or

mAh = Wh × 1000 / V

## Example

Find the electric charge in milliamp-hour when the energy consumption is 3 watt-hour and the voltage is 5 volts.

The electric charge Q is equal to 3 watt-hour times 1000, divided by 5 volts:

Q= 3Wh × 1000 / 5V = 600mAh
