The Convert Watt-Hours to mAh Calculator is a tool designed to simplify the process of converting the energy storage capacity of batteries from watt-hours (Wh) to milliampere-hours (mAh). This conversion is vital for individuals dealing with various electronic devices and systems, as it helps in estimating battery life and compatibility with different devices based on their power consumption.
The calculator leverages a straightforward formula, taking into account the voltage of the battery, to provide accurate conversions. By inputting the Wh value and the battery's voltage, users can instantly get the mAh value, making this tool indispensable for engineers, technicians, and gadget enthusiasts alike.
Formula of Convert Watt-Hours to mAH Calculator
The foundation of the calculator's functionality is the formula:
mAh=WhV×1000mAh=VWh×1000
Here's what each part of the formula represents:
- mAh: Milliampere-hours, the unit you are converting to.
- Wh: Watt-hours, the unit you are converting from.
- V: Voltage of the battery, in Volts.
- 1000: Conversion factor to account for the difference between milliamps and amps (and hours and milliseconds).
