The Amp Hours to Watt-Hours Calculator is a vital tool designed to convert the energy capacity of batteries from amp-hours (Ah) to watt-hours (Wh). This conversion is essential for understanding the total energy a battery can store and deliver at a given voltage. Such a calculator proves invaluable for a range of applications, from sizing solar power systems to determining the runtime of backup power sources.
Formula of Amp Hours to Watt-Hours Calculator
The core of this calculator's functionality is based on the formula:
Wh = Ah x V
where:
Whis watt-hours (energy),Ahis amp-hours (battery capacity),Vis voltage (electrical pressure).
This formula is pivotal in calculating the energy capacity of batteries, enabling users to make informed decisions about battery selection and energy consumption.

This table illustrates how varying amp-hour ratings convert to watt-hours at a common voltage, providing a useful tool for quick estimations.
Example of Amp Hours to Watt-Hours Calculator
Let's consider a practical example: a battery with a capacity of 100 amp-hours (Ah) at a voltage of 12 volts (V). Using the formula provided, we can calculate the battery's energy capacity in watt-hours (Wh).
Wh = 100 Ah x 12 V = 1200 Wh
This calculation shows that the battery can store 1200 watt-hours of energy, offering a clear insight into its storage capabilities.
Most Common FAQs
A1: Yes, the Amp Hours to Watt-Hours Calculator is versatile and can be used for any battery type, as long as you know the battery's amp-hour rating and its voltage.
A2: Voltage plays a critical role in the conversion process. A higher voltage means more electrical pressure, which, when multiplied by the amp-hour rating, results in a higher watt-hour value. Indicating more energy storage and delivery capacity.
A3: Yes, to convert watt-hours back to amp-hours, you use the formula:Ah = Wh / V
This formula helps determine the amp-hour rating from the energy capacity (Wh) and the voltage (V). Useful for reverse-engineering or verifying battery specifications.
