What does kilovolt ampere (kV*A) measure?

Kilovolt ampere is a unit of apparent power in AC electrical systems representing the product of RMS voltage and current without considering the power factor.

When would I need to convert kV*A to femtojoule/second?

This conversion helps compare large electrical power measurements to extremely small power levels encountered in nanoelectronics and experimental physics.

Can this tool convert apparent power to real power?

No, since kV*A measures apparent power, converting to real power requires additional information about the power factor.

What Is This Tool?

This unit converter transforms power measurements from kilovolt ampere (kV*A), commonly used in electrical engineering to express apparent power, into femtojoule per second (fJ/s), a unit ideal for quantifying ultra-small power in advanced physics and nanoelectronic applications.

How to Use This Tool?

Enter the power value in kilovolt ampere (kV*A) you want to convert
Select kilovolt ampere [kV*A] as the original unit and femtojoule per second [fJ/s] as the target unit
Click or tap the convert button to get the equivalent femtojoule/second value
Review the results which reflect the power conversion based on the defined rate of 1 kV*A = 10^18 fJ/s

Key Features

Converts apparent power units from kV*A to fJ/s accurately based on defined conversion rate
Useful for bridging scales between large electrical power systems and extremely low power physics measurements
Browser-based and easy to use with straightforward input and output interface
Supports understanding of power in both industrial and scientific contexts

Examples

Converting 2 kV*A results in 2 × 10^18 fJ/s
0.5 kV*A equals 5 × 10^17 fJ/s
These examples illustrate the scale difference between common electrical power units and ultra-small power units used in specialized fields

Common Use Cases

Rating of transformers, generators and UPS systems based on apparent power
Specifying capacity of electrical distribution equipment in buildings and data centers
Estimating total load including reactive power components in industrial power system design
Analyzing energy dissipation and power levels in nanoelectronic circuits and experimental physics
Facilitating power comparisons across vastly different magnitudes in research contexts

Tips & Best Practices

Ensure correct identification of units when converting power values to avoid confusion between apparent and real power
Use this converter primarily for understanding and comparing power levels rather than exact real power calculations
Verify unit input carefully to maintain the integrity of analyses involving very large or very small power units
Consider the context of power factor in AC systems since kilovolt ampere represents apparent, not real, power

Limitations

Kilovolt ampere measures apparent power without accounting for power factor, so real power cannot be directly derived
Femtojoule/second units apply to extremely low power levels and may have limited practical equivalence with high power units in some situations
Conversion is mainly useful for theoretical comparisons and specialized research rather than direct operational power calculations
