Watt Hours To Amp Hours Conversion (Wh To Ah): Calculator + Chart

Watt-hours and amp-hours are both units for electric charge.

1 watt-hour is defined as 1 watt of power expended for 1 hour.

1 amp hour is defined as 1 amp of current expended for 1 hour.

How do you convert watt-hours to amp-hours?

It is possible to convert watt-hours to amp-hours using the following formula:

Watt-hours = Amp-hours * Volts

To calculate amp-hours from watt-hours, we need to rearrange this equation to:

Amp-hours = Watt-hours / Volts

For the watt-hour to amp-hour conversion, you also need voltage (V).

Here is a nifty calculator that converts watt-hours to amp-hours. Further on, you’ll also find a chart of Wh to Ah for 120V and 220V.
