### Watt-hours to milliamp-hours calculation formula

So The electric charge Q(mAh) in milliamp-hours (mAh) is equal to  times the energy E(Wh) in watt-hours (Wh) divided by the voltage V(V) in volts (V).

Q(mAh) = 1000 × E(Wh) / V(V)

So milliamp-hours is equal to 1000 times watt-hours divided by volts:

milliamp-hours = 1000 × watt-hours / volts

or

mAh = 1000 × Wh / V

#### Example 1

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

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

Q = 1000 × 3Wh / 3V = 1000mAh

#### Example 2

Find the electric charge in milliamp-hours when the energy consumption is 3 watt-hours and the voltage is 6 volts.

The electric charge Q is equal to 1000 times 3 watt-hours, divided by 6 volts:

Q = 1000 × 3Wh / 6V = 500mAh

#### Example 3

Find the electric charge in milliamp-hours when the energy consumption is 13 watt-hours and the voltage is 5 volts.

The electric charge Q is equal to 1000 times 13 watt-hours, divided by 5 volts:

Q = 1000 × 13Wh / 5V = 2600mAh

#### Example 4

Find the electric charge in milliamp-hours when the energy consumption is 40 watt-hours and the voltage is 5 volts.

The electric charge Q is equal to 1000 times 40 watt-hours, divided by 5 volts:

Q = 1000 × 40Wh / 5V = 8000mAh
