## Ah to kWh Formula

The formula to convert an energy value from ampere-hours to kilowatt-hours is** kWh = (Ah x V) / 1000**.

Or

Where **Ah **is the energy value in amp-hours, **V** is the voltage of the energy source, and **kWh** is the equivalent energy value in kilowatt-hours.

## How to convert amp-hours to kilowatt-hours?

To convert energy value from amp-hours to kilowatt-hours, follow the simple steps below:

- Write down the energy value in amp-hours (Ah).
**Multiply**it by the value of the energy source voltage (V).**Divide**the result by 1000.- The result from the equation is the value of an energy value in kilowatt-hours (kWh).

Example: Find the maximum energy that can be produced by a 12V battery

What is the maximum energy can a 12V battery rated at 100Ah generates in kWh? Assuming it can use 100% of its capacity.

To find the maximum generated energy by the battery in kilowatt-hours or kWh, use the following formula and follows by entering the given values.

Therefore,

So, the maximum energy generated by a 12V battery with a capacity rated at 100Ah is **1.2 kWh.**
