What Is This Tool?
This converter allows you to transform values from femtojoule per second, a unit representing very small power measurements, into volt ampere, which measures apparent power in alternating current circuits.
How to Use This Tool?
-
Enter the value in femtojoule per second (fJ/s) that you wish to convert.
-
Select femtojoule per second as the input unit and volt ampere as the output unit.
-
Click convert to receive the equivalent power value in volt ampere (V*A).
Key Features
-
Converts femtojoule per second (fJ/s) to volt ampere (V*A) accurately based on unit equivalence.
-
Supports power measurements in nanoelectronics, quantum physics, and electrical engineering.

Browser-based and easy to use with straightforward input and output fields.
Examples
-
5 femtojoule/second corresponds to 5 × 10^-15 volt ampere.
-
10 femtojoule/second equals 1 × 10^-14 volt ampere.
Common Use Cases
-
Estimate energy dissipation per switching event in ultra-low-power nanoelectronic circuits.
-
Describe power levels in single-photon detectors or molecular-scale devices.
-
Rate transformers and UPS systems by apparent power capacity in electrical engineering.
Tips & Best Practices
-
Confirm the context—use femtojoule per second for very small power measurements often in experimental physics.
-
Remember volt ampere reflects apparent power and may differ from real power depending on power factor.
-
Utilize the tool to compare or integrate measurements across quantum scale and electrical engineering.
Limitations
-
The conversion treats femtojoule per second and volt ampere as equivalent units of power theoretically.
-
Volt ampere represents apparent power in AC circuits which may not match actual usable power if power factor is not 1.
-
Practical applications require caution due to differences between real power and apparent power.
Frequently Asked Questions
-
What does femtojoule per second measure?
-
It measures extremely small rates of energy transfer or power, commonly used in nanoelectronic and quantum physics contexts.
-
What is volt ampere used for?
-
Volt ampere represents apparent power in AC circuits and is used to rate electrical equipment like transformers and UPS units.
-
Is the conversion between femtojoule/second and volt ampere exact in practical systems?
-
No, because volt ampere accounts for apparent power which may differ from real power depending on the AC circuit's power factor.
Key Terminology
-
Femtojoule per second (fJ/s)
-
