Converting amp hours (Ah) to watt hours (Wh) is essential for understanding battery capacity and energy consumption. The formula for this conversion is straightforward: Wh = Ah × V, where V represents the voltage. For example, if you have a battery rated at 100 Ah and a voltage of 12V, the calculation would yield 1200 Wh. This conversion is vital for optimizing energy management in various applications.
Understanding Amp Hours and Watt Hours
Converting amp hours (Ah) to watt hours (Wh) is a straightforward process. To find the watt hours, simply multiply the amp hours by the voltage. The formula is: Wh = Ah * V. For example, if you have a 150 Ah battery with a voltage of 24V, the calculation would be 150 Ah * 24V = 3600 Wh. For easy and accurate conversions at various voltage levels, utilize our interactive amp hours to watt hours conversion calculator.

Watt-hours (Wh):
1. Definitions
- Amp Hours (Ah): A unit of electric charge that indicates how many amps a battery can deliver over one hour. It is commonly used to describe the capacity of batteries.
- Watt Hours (Wh): A unit of energy that measures the total amount of electricity consumed over time. It indicates how much power is used in one hour.
2. The Relationship Between Ah and Wh
The relationship between amp hours and watt hours can be expressed through the formula: Wh=Ah×V. This equation allows users to convert between these two measurements, facilitating better understanding and comparison of battery capacities.
Calculating Ah to Wh
1. Example Calculation
To illustrate how to convert amp hours to watt hours, consider a battery with a capacity of 150 Ah and a voltage of 24V:Wh=150 Ah×24 V=3600 Wh. This calculation indicates that the battery can provide 3600 watt hours of energy.
2. Practical Applications
Understanding how to convert Ah to Wh is crucial for determining how long a battery can power specific devices. For instance, if you have a device that consumes 600 watts, you can estimate its runtime using: Runtime hours =Wh/Power W. Using our previous example:Runtime=3600 Wh/600 W=6 hours.

Comparison of Battery Capacities
When comparing batteries, it’s essential to understand that watt hours alone do not provide a complete picture of energy capacity. For example, two batteries may have the same watt hour rating but different amp hour ratings due to their voltage differences.
| Battery Type | Voltage (V) | Capacity (Ah) | Total Capacity (Wh) |
|---|---|---|---|
| Battery A | 12 | 100 | 1200 |
| Battery B | 24 | 50 | 1200 |
| Battery C | 12 | 200 | 2400 |
In this comparison, both Battery A and Battery B provide the same total capacity in watt hours but differ in their amp hour ratings due to their voltage differences.
