Convert mAh to Ah

While electrical equations can look daunting at first glance, thankfully, most of the variables used are interlinked. This means that it’s pretty easy to work out important specifications even if you only have a couple of values, including being able to convert mAh (milliamp-hours) to Ah (amp-hours).

Understanding solar panels and solar batteries is essential when you want to use solar energy in your home. Because you can only collect the sun’s energy during the day, you need to store that electricity in a solar battery for when it gets dark. 

So, how do you know the battery will last as long as you need if you only know the milliamp-hours measurement? To do this, you need to convert mAh to Ah, and this guide explains exactly how through a clear explanation of the calculation and a practical example. 

Why Would You Convert mAh to Ah?

Our solar calculators can help you find units of measurement you don’t know, using the ones you do know. For example, to convert volts to amps, you only need to know the volts and watts. To convert mAh to Ah, you need to understand the terms milliamp-hours (mAh) and amp-hours (Ah).

The rate at which electricity flows is referred to as electrical current. That current is measured in amperes, usually referred to as amps. This unit of power can be scaled down by three orders of magnitude to give you a milliamp. 

So you want to know how many amps your battery can provide per hour?  That’s where amp-hours and milliamp hours come in. These units describe the number of amps your battery provides before it’s discharged. Just like amps can be converted to milliamps, amp-hours can be converted to milliamp-hours and vice versa

But what if you know your battery’s milliamp-hour rating and need to know the amp-hours? Or perhaps you want the amp-hours to use an Ah to kWh calculator? In these instances, you need to convert mAh to Ah. 

The calculation below shows you how to do it. 

How to Convert mAh to Ah

1 Ah = 1,000 mAh

So, to convert milliampere-hours to ampere-hours, remember that:1 mAh is equal to 0.001 Ah

To convert mAh to Ah, you need to divide the mAh by 1,000 to get to the Ah. You do the same thing to convert milliamps to amps and divide it by 1,000.

Example of How to Convert mAh to Ah

To better illustrate this calculation, we’re going to use one of our products as an example. 

Your neighbor said you can use his 12v lifepo4 battery. He tells you it provides 206,000 mAh. A battery that has a higher capacity takes longer to discharge than a battery with a lower capacity.

But, you want to know how many amp hours this battery provides you. So you take the mAh, which is 206,000, and divide it by 1,000. The answer is  206. 

Therefore, the battery produces 206 Ah. This means that the battery allows 206 amps of current to flow in 1 hour, or 1 amp for 206 hours. 

Once you’ve used a home amp calculator or an RV amp calculator to calculate the amount of current you need, you’ll know if the battery you’re looking at is suitable for your needs.

Conclusion

To ensure that your setup meets your needs, you have to do some basic calculations. Now you know how to convert mah to ah. You can also figure out how much use you’ll get from your batteries before they need discharge.
