What does one volt ampere represent?

One volt ampere (V*A) is the unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current, representing total delivered power regardless of phase angle.

When is converting V*A to mW exact?

The conversion is exact only when the power factor is 1, meaning the load is purely resistive and apparent power equals real power.

Why convert volt ampere to milliwatt?

Converting to milliwatt allows expressing apparent power in smaller units suitable for detailed engineering calculations and comparing power levels with real power measurements.

Select volt ampere as the source unit and milliwatt as the target unit.
Click the convert button to get the equivalent milliwatt value.

Key Features

Converts apparent power in volt amperes to milliwatts.
Browser-based and easy to use without installation.
Supports power units relevant for AC circuits and low power measurements.

Examples

2 V*A converts to 2000 mW
0.5 V*A equals 500 mW

Common Use Cases

Rating transformers, UPS, and generators by apparent power capacity.
Specifying electrical distribution and circuit protection equipment limits.

Tips & Best Practices

Confirm power factor when interpreting results since volt ampere measures apparent power including reactive components.
Use this conversion for expressing apparent power in smaller units suitable for low-power device specifications.
Employ milliwatt values to integrate apparent power with real power data when power factor is close to 1.

Limitations

Conversion assumes power factor of 1 for exact equivalence; otherwise, values can be misleading without knowing power factor data.
Volt ampere measures apparent power while milliwatt measures real power, so they represent different concepts in most AC systems.
