kVA to Watts Calculator
Convert kVA to Watts easily with this free calculator. Enter kVA and power factor (PF) to get watts (W). Ideal for electrical load and power system calculations.

Quick Intro: Convert kVA to Watts
This calculator converts apparent power in kVA to real power in watts using the power factor. It’s useful for accurately estimating the usable power in electrical systems.
Formula to Convert kVA to Watts
- Watts (W) = kVA × Power Factor × 1000
- Power Factor (PF) ranges between 0 and 1.
Example: 10 kVA × 0.8 PF × 1000 = 8000 W

Frequently Asked Questions - kVA to Watts Calculator:
How do I convert kVA to watts?
Multiply kVA by power factor and 1000: Watts = kVA × PF × 1000.
What is power factor?
Ratio of real power to apparent power, between 0 and 1.
What is the formula for kVA to watts?
Watts = kVA × Power Factor × 1000.
What is kVA?
Kilovolt-amps, a measure of apparent power.
Is watts less than kVA?
Yes, watts is real power, usually less due to PF.
Can I use this for single-phase or three-phase?
