How to Use the Milliwatt Calculator

This calculator helps you convert electrical power between different units and calculate power consumption based on voltage and current.

  1. Enter the value of power in watts, milliwatts, or kilowatts. Only one field should be filled at a time.
  2. Enter the voltage and current values if you want to calculate power consumption.
  3. Click the "Calculate" button to get the results.
  4. The results will display the power in watts, milliwatts, and kilowatts.

Conversion Formulas

1 Watt (W) = 1000 Milliwatts (mW)
1 Kilowatt (kW) = 1000 Watts (W)

Principle of Calculation

The calculator uses the formula: Power (P) = Voltage (V) × Current (I) to calculate power consumption in watts. It then converts the power to milliwatts and kilowatts.
