Enter the total number of amp hours and the total number of volts into the calculator to determine the equivalent Watts hours.

## Amp Hour to Watt Hour Formula

The following formula is used to convert amp-hours to watt-hours.

Wh = Ah * V

- Where Wh is watt hours
- Ah is amp hours
- V is the voltage (volts)

## Amp Hour to Watt Hour Definitin

Amp-hour to watt-hour is a conversion of total amps per hour to total watts per hour.

## Amp Hour to Watt Hour Example

The following is an example of how you can convert amp-hours into watt-hours using the formula above.

- First, you need to determine the total amp-hours. Recall that this is not the same as straight amps. It’s a rate of amps per hour. For this example, we will say that value is 50 Ah.
- Next, determine the voltage of the system. We will assume this to be 50 Volts.
- Finally, calculate the watt-hours using the formula above. 50 Ah * 50 Volts = 2,500 Wh.
