*How do I convert kilowatt-hours to amp-hours?*

In many cases, we need to convert kWh to Ah. With smaller 12V batteries, we also need to convert kWh to mAh.

We will look into how does kWh to amp-hours (Ah) conversion. You will also find a **kWh to Ah calculator** that dynamically calculated kWh from Ah and a calculated table of kWh to Ah and kWh to mAh. Let’s start with an example to illustrate.

*Example:* How to convert 13.5 kWh to Ah? First, we need to specify the voltage. Let’s say we have a 12V battery. We can calculate Ah from kWh using the basic kilowatt-hour equation:

**kWh = Ah Ã— V Ã— 1,000**

We express amp-hours (Ah) and insert our numbers:

**Ah = kWh Ã· V Ã— 1,000**

**Ah = 13.5kWh Ã· 12V Ã— 1,000 = 1,125 Ah**

That means that 13.5 kWh is equal to 1,125 Ah or 1,125,000 mAh on a 12V circuit.

Here is the kWh to Ah calculator that makes this calculation automatically:

## kWh To Ah Calculator

Just insert kWh and voltage (V), and you will get the calculated Ah. You can also play around with numbers a bit and the calculator will dynamically calculate the ampere-hours:

For example, it is useful to know this basic conversion:

**1 kWh** to Ah in a *12V* battery is equal to **83.33 Ah**.

On the other hand, if you need an Ah to kWh conversion, you can find a similar Ah to kWh conversion calculator here.

Here is the full calculated table of kWh to Ah conversions for the 12V circuit:
