Conversion / Calculation Guide
To convert volts to mAh, you must know watt-hours (Wh).
The formula is:
Step-by-step Example:
Given:
Voltage (V) = 5V
Energy (Wh) = 10Wh
Step 1: Multiply Wh by 1000
10 × 1000 = 10,000
Step 2: Divide by voltage
10,000 ÷ 5 = 2000 mAh
Final Answer:
Battery capacity = 2000 mAh
Key Notes
- You cannot convert volts to mAh directly without Wh.
- Voltage shows electrical pressure.
- mAh shows battery capacity.

Unit Standardization: SI vs. Imperial Sizing in Volts to mAh
When working with Volts to mAh calculations, using consistent physical units is vital. Small translation errors between SI Metric units (like millimeters, kilowatts, and meters) and Imperial units (like AWG wire, horsepower, and feet) can lead to serious sizing errors:
| Dimension | SI Metric Unit | Imperial Unit | Conversion Conversion Factor |
|---|---|---|---|
| Power | Kilowatts (kW) | Horsepower (HP) | 1 kW ≈ 1.341 HP |
| Length | Meters (m) | Feet (ft) | 1 m ≈ 3.2808 ft |
| Flow Rate | Cubic meters/hr (m³/h) | Gallons/minute (GPM) | 1 m³/h ≈ 4.403 GPM |
Always perform unit checks before installing physical components for Volts to mAh to ensure they match equipment specification sheets.
