The mWh to mAh calculator is an essential tool for converting the energy stored in a battery from milliwatt-hours (mWh) to milliampere-hours (mAh). This conversion is crucial for understanding how long a battery will last under a specific load, making it invaluable for designing and optimizing electronic devices. The calculator simplifies the process, allowing users to input the energy in mWh and the voltage in volts to receive the capacity in mAh.
Formula of mWh to mAh Calculator
The conversion from mWh to mAh involves a simple formula:
mAh = mWh / V
Where:
mWhis the energy in milliwatt-hours.mAhis the capacity in milliampere-hours.Vis the voltage in volts.
This formula is the cornerstone of the calculator, providing a quick and accurate way to perform conversions.
Conversion Table
| Voltage (V) | Energy in mWh | Capacity in mAh |
|---|---|---|
| 3.7 | 1000 | 270 |
| 3.7 | 2000 | 541 |
| 5.0 | 1000 | 200 |
| 5.0 | 2000 | 400 |
| 7.4 | 1000 | 135 |
| 7.4 | 2000 | 270 |
Energy in mWh: The energy capacity of the battery expressed in milliwatt-hours.
Capacity in mAh: The resulting battery capacity in milliampere-hours after conversion.
Example of mWh to mAh Calculator
For practical understanding, consider a battery with an energy storage of 5000 mWh at a voltage of 5 volts. Using the formula:
mAh = 5000 mWh / 5 V = 1000 mAh
This example demonstrates how to calculate the capacity in milliampere-hours from milliwatt-hours, providing a clear, real-world application of the conversion formula.
Most Common FAQs
Use the formula mAh = mWh / V, where mWh is the energy in milliwatt-hours, mAh is the capacity in milliampere-hours, and V is the voltage in volts.
Voltage is crucial because it determines how much current a battery can deliver over time, affecting the conversion from mWh to mAh. It ensures the accuracy of the conversion by accounting for the electrical potential difference.
Yes, the mWh to mAh calculator is versatile and can be used for any battery type, as long as you know the battery’s energy in mWh and its voltage.
