## kWh to Ah Formula

The formula to convert an energy value from kilowatt-hours to ampere-hours is** Ah = (kWh x 1,000) / V**.

Or

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

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

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

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

Example: Find the energy capacity of a 12V battery

What is the energy capacity of a 12V battery that can produce 0.7 kWh of electric energy? Assuming it can use 100% of its capacity.

To find the energy capacity of the battery in amp-hours or Ah, use the following formula and follows by entering the given values.

Therefore,

So the energy capacity of the 12V battery is **58.33 Ah.**
