What is MWh and mAh?

  • Mega Watt-Hour (MWh):
    A unit of energy equal to one million watt-hours. Typically used to measure large-scale energy generation or consumption (e.g., power plants, industrial usage).
  • Milliamp-hour (mAh):
    A measure of electric charge commonly used to describe the capacity of small batteries (e.g., smartphone batteries). It represents the amount of current a battery can deliver over time.

Converting MWh to mAh helps relate large energy amounts to battery capacities, useful for battery sizing, performance analysis, or energy storage calculations.

  5. Reset if Needed:
    Use the reset button to clear inputs and perform a new calculation.

How the Calculator Works

The conversion formula used by the calculator is: mAh=(MWh×1,000,000Voltage)×1000mAh = \left(\frac{MWh \times 1,000,000}{Voltage}\right) \times 1000mAh=(VoltageMWh×1,000,000​)×1000

Explanation:

  • 1 MWh = 1,000,000 Wh (watt-hours).
  • Amp-hours (Ah) = Wh ÷ Voltage (V).
  • Milliamp-hours (mAh) = Ah × 1000.

This formula converts the energy from Mega Watt-Hours into milliamp-hours by adjusting for voltage and scaling the unit properly.

Example Calculation

Suppose you have 0.5 MWh of energy and want to find out the equivalent mAh at 12 volts.

  • Energy (MWh): 0.5
  • Voltage (V): 12

Step-by-step calculation:

  1. Convert MWh to Wh:
    0.5×1,000,000=500,0000.5 \times 1,000,000 = 500,0000.5×1,000,000=500,000 Wh
  2. Calculate Ah:
    500,000÷12=41,666.67500,000 \div 12 = 41,666.67500,000÷12=41,666.67 Ah
  3. Convert Ah to mAh:
    41,666.67×1000=41,666,66741,666.67 \times 1000 = 41,666,66741,666.67×1000=41,666,667 mAh

Result: 41,666,667 mAh

You can input these values into the calculator and get this result instantly, saving time and ensuring accuracy.
