The mAh to Watt Hour Calculator is an essential tool designed to convert battery capacity from milliamp hours (mAh) to watt hours (Wh). This conversion is crucial for understanding the energy a battery can store, which allows consumers, technicians, and enthusiasts to compare and assess batteries across different devices and applications. The calculator simplifies the process, providing a quick, accurate, and user-friendly means of conversion.
Formula of mAH to Watt Hour Calculator
Wh = mAh * V / 1000
- Wh – Watt hours (the unit of energy you’re converting to)
- mAh – Milliamp hours (the battery capacity value you’re starting with)
- V – Voltage (of the battery)
- / 1000 – Conversion factor to account for the difference in unit sizes (milliamps to amps and milliamp hours to watt hours)
Understanding this formula is critical for accurately converting mAh to Wh, ensuring that users can effectively calculate the energy storage capacity of batteries.
Table for General Terms
| Battery Capacity (mAh) | Voltage (V) | Watt Hours (Wh) |
|---|---|---|
| 500 | 3.7 | 1.85 |
| 1000 | 3.7 | 3.7 |
| 1500 | 3.7 | 5.55 |
| 2000 | 3.7 | 7.4 |
| 2500 | 3.7 | 9.25 |
| 3000 | 3.7 | 11.1 |
| 3500 | 3.7 | 12.95 |
| 4000 | 3.7 | 14.8 |
This table assumes a common voltage of 3.7 V, which is typical for many lithium-ion batteries used in consumer electronics such as smartphones and laptops.
Example of mAH to Watt Hour Calculator
To illustrate, let’s convert 1000 mAh at 3.7 V to watt hours:
Wh = 1000 * 3.7 / 1000 = 3.7 Wh
This example shows that a battery with a capacity of 1000 mAh operating at 3.7 volts stores 3.7 watt hours of energy.
Most Common FAQs
mAh stands for milliamp hours, a unit that measures electric charge and represents the capacity of a battery.
The voltage of a battery is usually print on the battery itself. Can be find in the device’s user manual or specification sheet.
Yes, this calculation applies universally to all battery types. But it’s essential to know the accurate voltage of the battery for precise conversions.
