To convert kilowatt hours to milliamp hours, the formula is **milliamp hours = (kilowatt hours / volts) x 1,000,000**.

For instance, if you have a device that consumes 1 kWh at 5 volts, the calculation would be (1 / 5) x 1,000,000 = 200,000 mAh.

## How to Convert Kilowatt Hours to Milliamp Hours (kWh to mAh)

To convert kilowatt hours to milliamp hours, divide kilowatt hours by volts and then multiply by 1,000,000.

**Conversion formula:** milliamp hours = kilowatt hours Ã· volts Ã— 1,000,000

**Abbreviated formula:** mAh = kWh Ã· V Ã— 1,000,000

### Example

For instance, let's take a 0.1 kilowatt-hour battery that operates at 3.7 volts, which is a common voltage for many rechargeable lithium-ion batteries.

To find the milliamp hours, you'd do the following:

0.1 kWh Ã· 3.7 V Ã— 1,000,000 = 27,027.027 mAh

So, the battery has a capacity of approximately 27,027 milliamp hours.

## How to Convert Milliamp Hours to Kilowatt Hours (mAh to kWh)

What about converting the other way?

To convert milliamp hours to kilowatt hours, multiply milliamp hours by volts and then divide by 1,000,000.

**Conversion formula:** kilowatt hours = milliamp hours Ã— volts Ã· 1,000,000

**Abbreviated formula:** kWh = mAh Ã— V Ã· 1,000,000

### Example

Suppose you have a laptop with a battery capacity of 5,000mAh and a voltage of 11.1V.

Here's how you'd find its battery capacity in kilowatt hours:

5,000 mAh Ã— 11.1 V Ã· 1,000,000 = 0.0555 kWh

This means your laptop battery has a capacity of 0.0555 kilowatt hours.
