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 × V × 1,000
We express amp-hours (Ah) and insert our numbers:
Ah = kWh ÷ V × 1,000
Ah = 13.5kWh ÷ 12V × 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:

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:
