How to Use the Amps to kW Calculator
- Select Current Type: Choose DC, AC Single Phase, or AC Three Phase from the dropdown.
- Enter Voltage (V): Input the voltage in volts (must be a positive number).
- Enter Current (A): Input the current in amps (must be a positive number).
- Enter Power Factor (if AC): For AC types, provide a power factor between 0 and 1 (e.g., 0.8). This field appears only for AC selections.
- Click "Calculate": The result shows power in kilowatts (kW) with the formula used.
Note: All inputs must be positive numbers. The calculator uses standard formulas: DC (V × A / 1000), Single Phase AC (V × A × PF / 1000), Three Phase AC (√3 × V × A × PF / 1000).

Frequently Asked Questions
For DC, kW = (Volts × Amps) / 1000. For single-phase AC, kW = (Volts × Amps × Power Factor) / 1000. For three-phase AC, kW = (√3 × Volts × Amps × Power Factor) / 1000.
Power factor is the ratio of real power to apparent power in an AC circuit, ranging from 0 to 1. It is 1 for purely resistive loads.
Yes, as long as you enter the correct voltage (in volts) and current (in amps), the calculator works for any value.
