# Milliamp Hours to Kilowatt Hours (mAh to kWh) Conversion Calculator

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

For example, if you have a 3.7V 10,000mAh battery pack, the calculation would be (10,000 x 3.7) / 1,000,000 = 0.037 kWh.

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

To convert milliamp hours to kilowatt hours, multiply milliamp hours by volts and then divide by 1,000,000. (And no, that's not a typo!)

Conversion formula: kilowatt hours = milliamp hours × volts ÷ 1,000,000

Abbreviated formula: kWh = mAh × V ÷ 1,000,000

### Example

Let's say you have a smartphone with a battery capacity of 3,000 milliamp hours (mAh) and a voltage of 3.7 volts.

To calculate your battery's kilowatt hours, you'd do the following:

`(3,000 mAh × 3.7 V) ÷ 1,000,000 = 0.0111 kWh`

So, your phone battery has a capacity of about 0.0111 kilowatt hours.

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

Need to convert the other way?

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 ÷ volts × 1,000,000

Abbreviated formula: mAh = kWh ÷ V × 1,000,000

### Example

Suppose you have a device that uses 0.05 kilowatt hours (kWh) of energy and operates at a voltage of 5 volts.

To find out how many milliamp hours (mAh) that is, you can do the following calculation:

`(0.05 kWh ÷ 5 V) × 1,000,000 = 10,000 mAh`

So, your device uses approximately 10,000 mAh of energy at 5 volts.
