This conversion tool facilitates the change between ampere-hours (Ah), a unit of electric charge, and kilowatt-hours (kWh), a unit of energy. For instance, a battery rated at 100 Ah at a voltage of 12V stores 1.2 kWh of energy (100 Ah * 12 V = 1200 Wh = 1.2 kWh). The voltage plays a critical role in this calculation as it represents the electrical potential difference, connecting charge and energy.
Accurately converting between these units is essential for various applications, including sizing battery systems for solar power storage, estimating the energy consumption of electronic devices, and understanding electricity bills. This allows for more informed decisions regarding energy storage and usage. Historically, the need for such conversions arose with the development and widespread adoption of battery-powered devices and renewable energy systems.
