What does volt ampere (V*A) measure?

Volt ampere is the unit of apparent power in alternating-current circuits, representing the product of root-mean-square voltage and current without considering phase angle.

Why convert volt ampere to gigajoule/second?

Converting to gigajoule/second allows expressing power at very large scales suitable for power plants, grid management, and engineering contexts dealing with GW-level power.

Does this conversion give real power values?

No, volt ampere measures apparent power; the real power depends on the power factor and is not directly provided by this conversion.

Key Features

Converts apparent power units from volt ampere (V*A) to gigajoule/second (GJ/s).
Supports electrical engineering and large-scale power analysis applications.
Browser-based and simple to use without additional software.
Provides standardized SI unit conversion useful for high-capacity power systems.

Examples

Convert 500 V*A to gigajoule/second: 500 V*A equals 5.0 × 10⁻⁷ GJ/s.
Convert 2,000,000 V*A to gigajoule/second: equals 2 × 10⁻³ GJ/s.

Common Use Cases

Rating and specifying transformers, UPS, and generators by their apparent power capacity.
Estimating electrical output capacity of large power plants and grid-scale generation.
Analyzing continuous thermal power from industrial boilers and combined-cycle plants.
Supporting aerospace engineering by measuring large mechanical or propulsive power.

Tips & Best Practices

Ensure the input value reflects apparent power, which may differ from real power depending on power factor.
Use this conversion for high-capacity power analysis where gigajoule/second units provide standardized scale.
Consider the effects of phase angle and reactive power separately, as this tool assumes steady-state conditions.

Limitations

Volt ampere measures apparent power, not directly real power without power factor consideration.
Gigajoule/second covers extremely large power values, so converted results may be very small numbers requiring careful interpretation.
Conversion assumes steady-state operation and consistent SI units; reactive power effects are not included.
