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.
