Amp Hour to Watt Hour (ah ↔ wh) Calculator

The Amp Hour to Watt Hour Calculator is a vital tool for anyone dealing with battery technology, solar energy systems, or any application where battery capacity and energy storage are relevant. This calculator helps in converting the capacity of a battery from ampere-hours (Ah), a measure of electrical charge, to watt-hours (Wh), a measure of electrical energy, providing a more comprehensive understanding of a battery’s storage capabilities.

Formula

The conversion from amp hours to watt hours is straightforward but crucial for proper energy management and planning:

• Battery Capacity (Ah): The capacity of the battery in ampere-hours (Ah).
• Voltage (V): The nominal voltage of the battery in volts (V).

Formula:

Detailed Calculation Steps:

1. Identify the Battery Capacity (Ah): Determine the total capacity of the battery in ampere-hours.
2. Determine the Voltage (V): Note the nominal voltage of the battery, typically provided by the manufacturer.
3. Calculate the Watt Hours (Wh): Multiply the ampere-hours by the voltage to convert the capacity to watt-hours.

Table for General Terms

To assist users in understanding common terms related to electrical measurements, the following table is provided:

Example

For instance, if you have a battery with a capacity of 100 Ah and a voltage of 12 V:

• Battery Capacity (Ah) = 100 Ah
• Voltage (V) = 12 V

Watt Hours (Wh) = 100 Ah × 12 V = 1200 Wh

This calculation shows that the battery can store 1200 watt-hours of energy, useful for determining how long the battery can run a particular appliance or system.
