Volts to kW Calculator
Quickly convert volts to kilowatts (kW) using this free calculator. Supports single and three-phase power systems. Accurate and easy-to-use for all electrical applications.

Quick Intro: Convert Volts to Kilowatts
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.
Formula to Convert Volts to Kilowatts
- DC Line: kW = (V × I) ÷ 1000
- Single-phase: kW = (V × I × PF) ÷ 1000
- Three-phase (Line to Line): kW = (√3 × V × I × PF) ÷ 1000
- Three-phase (Line to Neutral): kW = (3 × V × I × PF) ÷ 1000
Where V = volts, I = current in amps, PF = power factor
