Ultimate Guide: How to Convert mAh to Ah?

When it comes to understanding battery life, one of the most useful electrical units you can use is the amp-hour (Ah) rating. It's the amount of energy stored in the battery and typically represents one amp flow of current in one hour. If a battery has a higher Ah value, it means it can charge appliances for long hours. However, sometimes, the battery or appliances indicate only the mAh value. That's where the mAh to Ah conversion formula comes in handy.

What is mAh to Ah?

A milliamp-hour (mAh) is one-thousandth of an amp-hour (Ah) that describes the energy or charge any battery can hold or for how long it can power appliances before it gets depleted. It is often used to rate the battery capacities for power tools, laptops, clocks, and smartphones. One 1mAh battery can deliver a continuous current of 1 mA for one hour. If the mAh value is higher, the battery will last for longer.

Many batteries often have Ah values written on them. It's the amount of energy charged in a battery that delivers one ampere or 1000 mAh of current flow in one hour. It can be calculated by simply multiplying the electric current and the discharge time.

The two units — mAh and Ah — are related using the following formula:

1 mAh = 0.001 Ah

Jackery Explorer Portable Power Stations have large NMC and LiFePO4 batteries. The ultimate power master, Jackery Explorer Portable Power Station, has a generous battery capacity of 3024Wh and is operated at 43.2V. The Ah rating of the battery is Ah = Wh ÷ V = 3024Wh ÷ 43.2V = 70Ah. With a high Ah and Wh rating, this battery backup can charge home appliances for long hours.

Jackery Explorer Portable Power Stations have a high Ah value and capacities. For example, the battery capacity of Jackery Explorer 3000 Pro Portable Power Station is rated at 70Ah. The mAh value can be calculated as 70Ah*1000 = 7000mAh. Besides, Jackery also offers other popular Jackery Explorer 1500 Pro Portable Power Station and Jackery Explorer 2000 Pro Portable Power Station that come with reasonable wattages and the ability to power most home or outdoor appliances.

How to Convert mAh to Ah?

In order to convert mAh to Ah, all you need to do is divide the mAh value by 1000. The electric charge in amp-hours equals the electric charge in milliamp-hours divided by 1000. Here is the mAh to Ah conversion formula:

Example 1: Suppose you are charging an NMC battery with a capacity of 20,000 mAh. Here's how to convert 20,000 mAh to Ah:

 Amp-hour rating = 20,000 mAh ÷ 1000 = 20 Ah

Example 2: If you have a battery with 10,000 mAh, the amp-hour will be calculated as follows. Here is how to convert 10,000 mAh to Ah:

Amp-hour rating = 10,000 mAh ÷ 1000 = 10 Ah

 Here are a few other common mAh to Ah conversions.

The rate at which electricity flows is called electrical current and is measured in amps. When you scale the power down of the unit by three orders, it gives you a milliamp. The conversion mAh to Ah formula is handy when you want to know how many amps the battery can provide per hour.

How to Convert Ah to mAh?

Similar to mAh to Ah conversion, it is easy to convert the amp-hours to milliamp hours. In order to change Ah to mAh, you'll need to multiply the milliamp-hour by 1000 to attain the amp-hour value. Here is the Ah to mAh formula:

Example: If you have a small 12V battery that has a capacity of 1.5 amp-hour, you can convert it using the above formula.

Milliamp-hour rating = 1.5 Ah × 1000 = 150 mAh

Here are a few other common Ah to mAh conversions.

mAh is a standard unit that measures electric charge in small batteries. Sometimes, the value is not specified directly on the battery or small appliance. Converting Ah to mAh will help you understand the capacity of small batteries or how long they can power small appliances.

mAh to Ah FAQs

Is 1000mAh equal to 1Ah?

Yes, 1000 milliamp-hour is equal to 1 ampere-hour rating. This is because one amp-hour is similar to one ampere of a continuous current flow for one long hour.

How much battery is 10,000 mAh?

A 10,000 mAh battery at 3.6V can provide 36W of power for 1 hour or 1W for 36 hours. If you have a battery capacity of 10,000 mAh, you can charge smartphones multiple times.

What does Ah mean on a battery?

Ampere-hour or Ah measures a battery's capacity. It typically indicates how many amps a specific battery can provide for one hour. Generally, a higher Ah battery will last longer than a battery with a lower Ah value. A battery with a high Ah value is best if you want to run heavy-duty devices like power tools.

What is the difference between Ah and Wh?

There are two critical electrical units — watt-hours and amp-hours — that determine how much energy you'll need to store in order to charge appliances. Wh (watt-hour) is the unit of energy that measures the power moving over time. In short, amp-hour (Ah) measures the battery's charge capacity, whereas watt-hour (Wh) is the energy capacity.

Final Thoughts

Amp and milliamp hours are the units of electric charge used to represent the battery capacities. Understanding these electrical terms will help you decide which battery backup can power your appliances and for how long. If you cannot find the Ah rating on the device, use the mAh to Ah conversion formula to get the amp-hour rating.

Jackery Explorer Portable Power Stations are available in different battery capacities with varied Wh and Ah ratings. You can choose the ultimate battery backup solution depending on how many appliances you want to charge and their power requirements. For example, the Jackery Explorer 2000 Pro with 2160Wh capacity can charge 96% of appliances, while the larger Jackery Explorer 3000 Pro can supply steady electricity to 99% of devices.
