Converting watt hours (Wh) to milliamp hours (mAh) is essential for understanding battery capacity, especially in smaller devices. The formula for this conversion is straightforward: mAh = (Wh × 1000) / V, where V is the voltage. For example, a battery rated at 2 Wh with a voltage of 5V would yield 400 mAh. This conversion is vital for optimizing energy management.
Understanding Watt Hours and Milliamp Hours
Converting watt hours (Wh) to milliamp hours (mAh) is a simple process. To perform the conversion, divide the watt hours by the voltage and then multiply by 1000. The formula is: mAh = (Wh / V) * 1000. For example, if you have a 15 Wh battery with a voltage of 3.7V, the calculation would be (15 Wh / 3.7V) * 1000 = 4054 mAh. To easily convert between these units and determine your battery’s milliamp hour capacity, use our watt hours to milliamp hours conversion calculator.

Milliamp-hours (mAh):
1. Definitions
- Watt Hours (Wh): A unit of energy that measures how much power is used over time. It indicates the total energy consumed or stored by a battery.
- Milliamp Hours (mAh): A unit of electric charge that represents how many milliamps a battery can deliver over one hour. It is commonly used to describe the capacity of smaller batteries, such as those in smartphones and portable devices.
2. The Relationship Between Wh and mAh
The relationship between watt hours and milliamp hours can be expressed through the formula:mAh=Wh×1000VThis equation allows users to convert between these two measurements, facilitating better understanding and comparison of battery capacities.
Calculating Wh to mAh
1. Example Calculation
To illustrate how to convert watt hours to milliamp hours, consider a battery with a capacity of 3 Wh and a voltage of 5V: mAh=3 Wh×1000/5 V=600 mAh. This calculation indicates that the battery can provide 600 milliamp hours of energy.
2. Practical Applications
Understanding how to convert Wh to mAh is crucial for determining how long a battery can power specific devices. For example, if you have a device that consumes 300 mA, you can estimate its runtime using:Runtime hours =mAhCurrent mA Using our previous example:Runtime=600 mAh / 300 mA = 2 hours.
Using a Calculator for Conversion
1. Online Conversion Tools
For quick and accurate conversions between watt hours and milliamp hours, online calculators are available. These tools allow users to input their specific Wh and voltage values, providing immediate results without manual calculations.
2. Manual Calculation Tips
When calculating manually, ensure that you have the correct voltage value for your specific battery system. Double-check your calculations for accuracy, especially when working with larger numbers.

Comparison of Battery Capacities
When comparing batteries, it’s essential to understand that milliamp hours alone do not provide a complete picture of energy capacity. For example, two batteries may have the same milliamp hour rating but different voltages, leading to different watt hour capacities.
| Battery Type | Voltage (V) | Capacity (mAh) | Total Capacity (Wh) |
|---|---|---|---|
| Battery A | 5 | 600 | 3 |
| Battery B | 12 | 250 | 3 |
| Battery C | 3.7 | 800 | 2.96 |
In this comparison, both Battery A and Battery B provide the same total capacity in watt hours but differ in their milliamp hour ratings due to their voltage differences.
