About this calculator
Overview
This calculator determines the power output of an electrical generator in kilowatts (kW) and kilovolt-amps (kVA) based on voltage, current, and the number of phases.
💡
Pro Tips
Standard household power is 1-phase, while industrial generators are often 3-phase.
Power Factor (PF) is usually around 0.8 for most loads, or 1.0 for purely resistive loads.
kW = kVA × Power Factor.

Fun Facts
"The massive generators at the Hoover Dam can produce over 2,000 megawatts of power."
"Portable household generators range from 2kW to 20kW to keep essential appliances running during outages."
"Alternators in cars are small generators that produce electricity to charge the battery and power electronics."
Formula: P(kW) = (V × I × PF × phaseFactor) / 1000
