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

Volts to Kilowatts Calculator Overview

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.

Frequently Asked Questions - Volts to kW Calculator:

How do I convert volts to kilowatts?

Use the formula: kW = (V × I × PF) ÷ 1000 for single-phase or include √3 for three-phase.

What is the formula for 3-phase conversion?

kW = (√3 × V × I × PF) ÷ 1000.

What does PF mean in the formula?

PF stands for power factor, which represents efficiency.

Can I convert volts to kW without amps?

No, you need both volts and amps to calculate power.

Is this calculator accurate for 3-phase power?

Yes, it supports 3-phase systems with √3 included.

What is a typical power factor?

Most systems have a PF between 0.8 and 1.

What’s the difference between kW and kVA?

kW is real power; kVA is apparent power.

Is this calculator suitable for industrial use?

Yes, it's accurate for industrial and commercial use.

Do I need to know voltage type?

Yes, specify whether it’s single or three-phase.

Is the volts to kW calculator free?

Yes, it's completely free and easy to use.
