What Is This Tool?
This online converter helps translate power values from volt ampere (VA), a unit for apparent power in AC circuits, to hectowatt (hW), a SI-derived unit equal to 100 watts. It simplifies converting electrical apparent power into a more straightforward unit scaled by hundreds of watts.

Common Use Cases
-
Rating transformers, UPS systems, and generators by apparent power
-
Specifying electrical distribution equipment capacity where voltage and current limits matter
-
Comparing device power consumption for small household loads and portable equipment
-
Performing electrical engineering calculations involving apparent and real power distinctions
Tips & Best Practices
-
Use this conversion when dealing with purely resistive loads or accept it as an approximation otherwise
-
Be aware that volt ampere measures apparent power, which may differ from real power
-
Consult additional units like watts or kilowatts for clearer power ratings in some cases
-
Leverage examples to better estimate power based on typical device outputs
Limitations
-
Volt ampere is a unit of apparent power and equals watts only when power factor is 1
-
Converting directly to hectowatt assumes either pure resistive loads or serves as an estimation
-
Hectowatt is less frequently used compared to watts or kilowatts, potentially causing confusion
Frequently Asked Questions
-
What does one volt-ampere represent in AC circuits?
-
One volt-ampere represents the apparent power, calculated as the product of root-mean-square voltage and current, regardless of phase angle.
-
How is a hectowatt related to watts?
-
A hectowatt equals 100 watts and uses the SI prefix hecto to scale the watt unit.
-
Can the volt-ampere value be directly used as real power?
-
Only if the power factor is 1, meaning the load is purely resistive; otherwise, volt-ampere measures apparent power, which differs from real power.
Key Terminology
