Free online amp hours to watt-hours (Ah to Wh) calculator – simply enter Amp-hours and Volts then click the calculate button.

## Amp Hours to Watt Hours Formula

To convert ah to wh, you can use the following formula

**Wh = Ah x v**

- Wh = kilowatt-hour
- Ah = Ampere-hour
- V = Voltage in volts

## How to Calculate Amp Hours to Watt Hours?

To calculate amp-hours to watt-hours, you need to multiply the amp-hours by the voltage of the battery.

For example, if you have a battery with a voltage of 12 volts and 3 amp hours, the watt hours would be 12 x 3, or 36 watt hours.
