This volts to kilowatts (kW) calculator helps you calculate electrical power based on input voltage, current, and power factor. The conversion is crucial in understanding how much real power an electrical system delivers. Choose between single-phase or three-phase settings for accurate results tailored to your needs.
Where V = volts, I = current in amps, PF = power factor
Use this online volts to kilowatts (kW) calculator to easily convert electrical voltage into power. It supports both single-phase and three-phase systems. Just enter the voltage, current, and power factor (if required), and get the real power output in kilowatts. Ideal for electricians, engineers, and students working with power systems.
| Volts (V) | Amps (I) | PF | kW (1-Phase) |
|---|---|---|---|
| 230 | 10 | 0.9 | 2.07 |
| 400 | 15 | 0.95 | 5.7 |
Use the formula: kW = (V × I × PF) ÷ 1000 for single-phase or include √3 for three-phase.
kW = (√3 × V × I × PF) ÷ 1000.
PF stands for power factor, which represents efficiency.
No, you need both volts and amps to calculate power.
Yes, it supports 3-phase systems with √3 included.
Most systems have a PF between 0.8 and 1.
