Watt-Hour To Milliamp-Hour (Wh To mAh) Conversion

Watt-hours, milliamp-hours, kilowatt-hours, and volts are common power and energy measuring units for electrical appliances and battery capacity. Using some simple formulas, you can easily convert Wh to mAh or vice versa.

When you plan to purchase a solar power station or a solar generator, it's vital to calculate the watt-hour and milliamp-hours. These units will help you understand how long the power station will charge your appliances or how quickly it will deplete.

A higher mAh and Wh rating battery can power your appliances for a long time before you'll need to recharge. Jackery Explorer Portable Power Stations have high Wh and mAh values, so you can keep your home or outdoor gear charged for more time.

In this guide, we will walk through what are watt-hour and milliamp-hour and how to convert mAh to Wh.

What Is Wh to mAh?

In layman's terms, watts represent the power any device takes to function. Watt-hour is the energy consumed by an appliance over a certain time period. The capacity of solar power stations is measured in watt-hours. It represents how much energy it can supply to devices in an hour.

Jackery Explorer Portable Power Stations have large battery capacities to keep your gear charged. For instance, you can choose Jackery Explorer 1000 Pro Portable Power Station to power basic home appliances, while Jackery Explorer 3000 Pro Portable Power Station can power 99% of most home electrical appliances.

A milliampere hour (mAh) describes the electric power over time and is commonly used to measure a battery's capacity. If a battery has a high mAh, the longer will be the battery capacity or life.

To convert Wh to mAh, divide the watt-hours by volts and multiply the equation by 1000.

Formula: Milliamp-Hour = Watt-Hour ÷ Volts / 1000

Abbreviated Formula: mAh = Wh ÷ V / 1000

Converting a battery's watt-hours to milliamp-hours is particularly helpful in deciding how fast you want to charge the power station. It can also help you estimate the battery's charge time to understand how long it will take your charger to power the battery. Lastly, the milliamp-hours help you to evaluate the battery's runtime, considering you know the current drawn by the appliance.

How to Convert Wh to mAh?

If the battery capacity is in watt-hours and you want to convert it into milliamp-hours, you will have to use a simple formula. As the direct conversion of Wh to mAh is not possible, you must include battery volts during the conversion.

Here is the mathematical formula to calculate the milliamp-hours, given that you have its watt-hour.

Q (Ah) = Wh ÷ V

To convert Ah to mAh, multiply the resultant by 1000.

Q (mAh) = Q (Ah) × 1000

Example:

Let's say you are using Jackery Explorer 1000 Pro battery capacity is 1002Wh, and the voltage is 43.2V. The milliamp-hours will be:

Q (Ah) = 1002 Wh ÷ 43.2 V = 23.2 Ah

Or, Q (mAh) = 23.2 Ah × 1000 = 23200 mAh.

That said, the portable power station has a 23.2 Ah battery.

Converting watt-hours to milliamp-hours assists you in understanding the battery's charge time. The larger the mAh battery of the solar generator, the more electrical energy it can store.

How to Convert mAh to Wh?

Generally, the device's battery capacity is in milliamp hours, and you must convert it into watt-hours. However, converting mAh to Wh is simple if you have battery volts.

Formula: Watt-Hour = Milliamp-Hour × Volts ÷ 1000

Abbreviated Formula: Wh = mAh × V ÷ 1000

Example 1:

Let us take an example of how to convert mAh to Wh.

Suppose you use a power station with a battery of 35000 mAh and 43.2V. You can substitute the values in the above formula.

Watt-Hour = 35000 mAh × 43.2V ÷ 1000 = 1512 Wh.

Example 2:

Suppose you use a smartphone with a 4500 mAh battery capacity in milliamp-hour and 3.7 V voltage. You can easily calculate the watt-hours by using the same formula.

Wh = 4500 mAh × 3.7V ÷ 1000 = 16.6 Wh

Converting mAh to Wh will help you compare the battery capacities of power stations or power banks with different voltages.

How to Convert kWh to mAh?

Kilowatt-hour or kWh is the measure of electrical energy equal to one thousand watts of power consumed in one hour. You can easily convert kWh into mAh using the below formula.

Formula: Ah = kWh × 1000 / V

The battery's electrical charge in amps is equal to the energy in kilowatt-hours times 1000, divided by voltage.

Let us take a simple example to understand better.

Suppose you want to convert 1kWh to mAh, where the battery voltage is 12V.

Ah = 1kWh × 1000 / 12V = 83.33 Ah

To convert Ah to mAh, multiply by 1000.

mAh = 83.33 Ah × 1000 = 83,330 mAh.
