What Is This Tool?
This converter allows you to transform power measurements from deciwatts, which represent small real power levels, to volt amperes, the unit of apparent power in AC circuits. It simplifies the conversion between these related but different units for practical use in electrical engineering and electronics.
How to Use This Tool?

Key Features
-
Converts power values from deciwatt [dW] to volt ampere [V*A]
-
Browser-based and easy to use interface
-
Supports understanding of apparent versus real power measurements
-
Useful for electrical engineering and electronics applications
Examples
-
5 deciwatts equals 0.5 volt amperes
-
10 deciwatts equals 1 volt ampere
Common Use Cases
-
Converting small-scale power measurements to apparent power in AC systems
-
Assessing ratings for electrical devices such as transformers and UPS units
-
Electrical engineering calculations for equipment and circuit design
-
Lab testing of low-power electronic components and sensors
Tips & Best Practices
-
Always consider the power factor when interpreting volt ampere values versus real power
-
Use this conversion when relating real power in deciwatts to apparent power ratings
-
Apply conversions in contexts involving AC electrical loads and device specifications
Limitations
-
Volt ampere measures apparent power and may differ from real power unless power factor equals 1
-
Conversion assumes understanding of power factor impact on power units
-
Deciwatt represents a measure of real power, so direct equivalence to volt amperes depends on AC load characteristics
Frequently Asked Questions
-
What does a deciwatt measure?
-
A deciwatt measures real power and is equal to one tenth of a watt, often used to specify low power levels in electronics.
-
What is a volt ampere used for?
-
The volt ampere represents apparent power in AC circuits and is used to rate equipment like transformers and UPS systems.
-
Does 1 deciwatt always equal 0.1 volt ampere?
-
Numerically, yes, but since volt ampere is apparent power and deciwatt is real power, their equivalence depends on the power factor of the load.
Key Terminology
-
Deciwatt [dW]
-
A unit of power equal to one tenth of a watt, used for expressing low levels of real power.
-
Volt ampere [V*A]
-
The unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current.
-
Apparent Power
-
The total power in an AC circuit, combining both real and reactive power, measured in volt amperes.
-
Power Factor
-
The ratio of real power to apparent power in an AC circuit, indicating how effectively the current is being converted to useful work.
