kWh to mAh Calculator
Instantly convert kilowatt-hours (kWh) to milliamp-hours (mAh) using voltage. Accurate battery capacity tool for energy, solar, and electronics projects.

Quick Intro: Convert kwh to mAh
The kWh to mAh Calculator lets you quickly convert kilowatt-hours to milliamp-hours by entering the energy value and voltage. This conversion is crucial when determining how much battery capacity is needed to store a given amount of energy. By using the formula:
mAh = (kWh × 1,000,000) / Voltage
you can estimate how much current in milliamp-hours a battery must provide to deliver a specific amount of energy. This is especially useful for solar installations, battery backups, and electric vehicles. The tool is straightforward, fast, and accurate perfect for professionals and DIY users alike.
Formula to Convert kwh to mAh
To convert kilowatt-hours (kWh) to milliamp-hours (mAh), use the following formula:
Where:
- kWh = Energy in kilowatt-hours
- V = Voltage in volts
- mAh = Resulting battery capacity in milliamp-hours
