What does volt ampere measure?

Volt ampere (V*A) measures apparent power in AC circuits and equals the product of RMS voltage and current, reflecting total delivered power regardless of phase angle.

How is kilowatt different from volt ampere?

Kilowatt (kW) measures real power or actual energy transfer rate, while volt ampere measures apparent power, which includes both real and reactive components.

Why does the power factor matter in conversion?

Power factor affects the ratio of real power to apparent power; without knowing it, converting V*A to kW may not give an accurate measure of actual power used.

Supports electrical engineering and power system applications.
Browser-based, user-friendly interface for quick calculations.
Includes example conversions for clarity.

Examples

Convert 500 V*A to kW results in 0.5 kW.
Convert 1500 V*A to kW results in 1.5 kW.

Common Use Cases

Rating transformers, UPS, and generators by apparent power capacity.
Specifying electrical distribution and circuit protection equipment.
Evaluating household and industrial power consumption.
Expressing generator and motor power output.
Determining HVAC equipment power capacity.
Converting between apparent power and real power for energy management.

Tips & Best Practices

Understand that volt ampere reflects total apparent power, which may not equal real power.
Consider the power factor when interpreting kilowatt values from volt amperes.
Use this conversion for estimates when power factor is close to 1 for accuracy.
Apply adjustments if the power factor differs from 1 to get precise real power.

Limitations

Volt ampere measures apparent power, not always matching actual power due to phase angle.
Kilowatt values from this conversion assume a power factor of 1 unless adjusted.
Without power factor data, converted kilowatts may not accurately represent actual power.
