*Watt-hours*, expressed together Wh or W·h, room a measure up of electric energy. Wh are usually used to measure the energy usage of a circuit or appliance.

The switch from electric charge to power requires the voltage and can it is in done making use of the formula below.

### mAh come Wh conversion Formula

Wh = (mAh × V) ÷ 1,000

Thus, the power in watt-hours is equal to the fee in milliamp-hours times the voltage, then divided by 1,000.

**For example,** transform the charge supplied by the typical C battery, i beg your pardon is 8,000 mAh in ~ 1.5 V, come Wh.
