Apparent Power Converter

What is Apparent Power?

Apparent Power is the total power in an AC circuit, combining both active power (watts) and reactive power (VAR). It is represented by the symbol S and measured in Volt-Amperes (VA).

Formula:

S = \sqrt{P^2 + Q^2}

Where:

 = Active Power (Watt)

 = Reactive Power (VAR)

 

Why Use an Apparent Power Converter?

• Instantly convert between VA, kVA, and MVA
• Useful for power system analysis
• Helps with transformer, generator, and UPS sizing
• Saves time for students and engineers

 

 Common Use Cases

• Transformer rating calculations
• Generator and UPS sizing
• Industrial load management
• AC power analysis for design & simulation

 

 How to Use the Apparent Power Converter

1. Enter the apparent power value.

2. Choose the input unit (VA, kVA, or MVA).

3. Instantly see conversions in all other units.

 

 Supported Units

• Volt-Ampere (VA)
• Kilovolt-Ampere (kVA) = 1,000 VA
• Megavolt-Ampere (MVA) = 1,000,000 VA
• Gigavolt-Ampere (GVA) = 1,000,000,000 VA

 

 Example Conversions

• 1 kVA = 1,000 VA
• 1 MVA = 1,000,000 VA
• 1 GVA = 1,000 MVA
• 750 VA = 0.75 kVA

 FAQs

1. What is the unit of apparent power?

It is measured in Volt-Amperes (VA).

2. How is apparent power different from real power?

Real Power (Watt) – Does useful work.

Apparent Power (VA) – Total power (includes reactive + real).

3. Why is apparent power important?

It determines the capacity of generators, transformers, and UPS systems.

4. How do I convert kVA to MVA?

Divide by 1,000 (e.g., 2500 kVA = 2.5 MVA).

5. Is this Apparent Power Converter free?

Yes – 100% free and online.
