What does volt ampere measure?

Volt ampere is a unit of apparent power in AC circuits, reflecting the product of RMS voltage and current regardless of phase angle.

When is the volt ampere equal to watt?

Volt ampere equals watt only when the power factor is 1, such as with purely resistive loads.

Why convert volt ampere to nanowatt?

Converting to nanowatt helps express large apparent power values in smaller units for analysis of tiny power consumption or output levels.

Tips & Best Practices

Remember volt ampere measures apparent power, which may differ from usable power depending on power factor.
Use the conversion to express large AC power values in very small units for precise reporting.
Ensure consistent measurement units and awareness of phase angle effects when interpreting results.

Limitations

Volt ampere indicates apparent power, not necessarily the real usable power without power factor consideration.
Nanowatt units are primarily for extremely low powers, so conversions imply scale rather than practical equivalence for large values.
Conversion accuracy assumes uniform units and does not account for phase angle influences in AC power.
