What Is This Tool?
This unit converter allows you to change measurements of power from volt amperes, a unit of apparent power in AC circuits, into dekajoules per second, an SI-derived unit of power that quantifies energy transfer rate.
How to Use This Tool?
-
Enter the value in volt amperes that you wish to convert
-
Select volt ampere [V*A] as the input unit
-
Choose dekajoule/second [daJ/s] as the target unit
-
Review the converted result, representing the power in dekajoules per second

Common Use Cases
-
Rating electrical equipment like transformers or UPS by their apparent power
-
Expressing power ratings of household appliances and lighting in an SI unit
-
Power systems design and energy management where translating apparent power into energy rates is necessary
-
Engineering and laboratory analysis of device power output using standardized units
Tips & Best Practices
-
Ensure power factor is considered when interpreting converted values, as volt ampere measures apparent power
-
Use the tool for approximate translation of apparent power into energy transfer rates when power factor is close to 1
-
Validate the context where real power versus apparent power distinction is critical before relying on conversions
-
Refer to the device specifications to understand the nature of power being measured
Limitations
-
Converted values exactly represent real power only if the power factor equals 1
-
Volt ampere measures apparent power, which differs from real power when the phase angle between voltage and current is not zero
-
Additional information regarding power factor is necessary to fully interpret converted power in dekajoule/second
-
This tool does not account for reactive power components in AC systems
Frequently Asked Questions
-
What does one volt ampere measure?
-
One volt ampere measures apparent power in AC circuits as the product of root-mean-square voltage and current, independent of phase angle.
-
How is dekajoule per second related to watts?
-
One dekajoule per second equals ten watts, and it represents a power measurement as the rate of energy transfer.
-
Why might the converted power differ from real power?
-
Because volt ampere measures apparent power, the converted value matches real power only when the power factor is one; otherwise, they represent different physical quantities.
Key Terminology
-
Volt ampere (V*A)
-
Unit of apparent power in AC circuits that equals the product of RMS voltage and RMS current, reflecting total delivered power regardless of phase.
-
Dekajoule per second (daJ/s)
-
SI-derived unit of power equal to 10 joules per second or 10 watts, used to measure energy transfer rate.
-
Apparent Power
-
The total power in an AC circuit calculated as the product of voltage and current without accounting for phase angle.
-
Power Factor
-
A dimensionless number representing the phase difference between voltage and current; when equal to 1, apparent power equals real power.
