kWh to Ah Conversion (Calculator: Input kWh and get V, Ah or mAh)

How do I convert kilowatt-hours to ampere-hours?

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

We’ll see how the conversion from kWh to amp-hours (Ah) takes place. you will also find kWh to Ah calculator Table that dynamically calculates Ah to kWh and 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 kWh to Ah using the basic kilowatt-hour equation:

kWh = Ah × V × 1,000

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

Ah = kWh V × 1,000

Ah = 13.5kWh 12V × 1,000 = 1,125 Ah

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

Here’s a kWh to Ah calculator that does this calculation automatically:

Just put in kWh and voltage (V), and you’ll get the calculated Ah. You can also play with the numbers a bit and the calculator will calculate the ampere-hour dynamically:

Calculated Ah (amp-hour)


For example, it’s useful to know this basic conversion:

1 kW to be in one 12th battery is equal to 83.33 Ah,

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

Here is a full calculation table of kWh to Ah conversions for a 12V circuit:

0.01 kW 0.83 Ah 830 mAh
0.02 kW 1.67 Ah 1,670 mAh
0.025 kW 2.5 Ah 2,500 mAh
0.05 kW 4.17 Ah 4,170 mAh
0.1 kW 8.33 Ah 8,330 mAh
0.5 kW 41.67 Ah 41,670 mAh
1 kW 83.33 Ah 83,330 mAh
2 kW 166.67 Ah 166,670 mAh
10 kW 833.33 Ah 833,330 mAh
20 kW 1,666.67 Ah n/a
50 kW 4,166.67 Ah n/a
100 kW 8,333.33 AH n/a
