## How to Convert Milliamp Hours to Milliamps (mAh to mA)

To convert milliamp hours to milliamps, divide milliamp hours by hours.

**Conversion formula:** milliamps = milliamp hours Ã· hours

**Abbreviated formula:** mA = mAh Ã· hrs

### Example

Let's say your electric toothbrush has a 500 mAh battery and it lasts for 1.5 hours. Here's how to find out to calculate its current draw in milliamps

1500 mAh Ã· 1.5 hours = 1000 mA

Your toothbrush is using 1000 milliamps when on.

### Why Convert Milliamp Hours to Milliamps?

Most electronics list how much current they use, in amps or milliamps. However, most devices also use varying levels of current depending on how you use them. (Your phone is consuming more power when you're streaming a video than when you're typing a note, for instance.)

So converting milliamp hours to milliamps can be useful when you're trying to estimate a device's average current draw.

For example, let's say you have a portable speaker with a 1200 mAh Li-ion battery. It lasts for 5 hours on a full charge. Here's how to estimate its average current draw:

1200 mAh Ã· 5 hrs = 240 mA

So, even though your speaker is using varying amounts of current from moment to moment depending on the volume level and other factors, you know that, on average, it's consuming around 240 milliamps.

## How to Convert Milliamps to Milliamp Hours (mA to mAh)

Need to convert the other way?

To convert milliamps to milliamp hours, multiply milliamps by hours.

**Conversion formula:** milliamp hours = milliamps Ã— hours

**Abbreviated formula:** mAh = mA Ã— hrs

### Example

Let's say you have an e-reader that uses 50 milliamps. It lasts around 30 hours on a full charge.

Here's how to calculate how many milliamp hours it consumes:

50 mA Ã— 30 hrs = 6000 mAh

So, your e-reader used 6000 milliamp hours of battery life in that time.

## How to Convert Milliamp Hours to Amps (mAh to A)

Sometimes you want to express a device's current in amps (A) rather than milliamps. There are 1000 milliamps in 1 amp, so, to convert milliamp hours to amps, we need to first convert milliamp hours to milliamps and then do 1 extra step: divide by 1000.

**Conversion formula:** amps = milliamp hours Ã· hours Ã· 1000

**Abbreviated formula:** A = mAh Ã· hrs Ã· 1000

### Example

Let's say you have a solar power bank and, after 8 hours in the sun, it has collected 2000 mAh of solar energy. What was the average current the solar panel was generating?

2000 mAh Ã· 8 hrs Ã· 1000 = 0.25 A

Your power bank's solar panel was generating, on average, around 0.25 amps.
