Optimize Electrical System Sizing

Accurately sizing electrical infrastructure requires precise apparent power calculations. Our Apparent Power Converter streamlines this process, enabling engineers and technicians to convert between Volt-Amperes (VA), kilovolt-amperes (kVA), and megavolt-amperes (MVA) instantly. This tool is essential for determining the capacity of transformers, generators, and UPS systems where total load handling capability is critical.

Apparent power (S) represents the vector sum of real power (which performs work) and reactive power (which sustains magnetic fields). By getting this conversion right, you prevent equipment overloading and ensure your electrical distribution system operates safely and efficiently.

How to Use

Input Data: Enter your measured apparent power value into the "From" field.
Select Scale: Choose your current unit (e.g., kVA) and target unit (e.g., MVA) from the dropdowns.
Calculate: Click "Convert Power" to instantly generate the precise equivalent.
Copy: Use the "Copy Result" button to save the figure for your technical reports.

Frequently Asked Questions

What is the purpose of apparent power?

Apparent power (S) defines the total capacity required for electrical equipment. It combines real working power with reactive power, ensuring transformers and generators are rated to handle the full current load without overheating.

How do you convert real power to apparent power?

Use the power factor formula: S (VA) = P (Watts) / Power Factor (PF). For example, if a motor consumes 800W at 0.8 PF, the apparent power required is 1000 VA (or 1 kVA).

What is the difference between apparent power and reactive power?

Apparent power (kVA) is the total power flowing in a circuit. Reactive power (kVAR) is the non-working portion maintaining magnetic fields. Real power (kW) performs the actual work.

Do you pay for real power or apparent power?

Homes pay for real power (kWh). Industrial facilities often pay for apparent power via demand charges or power factor penalties, incentivizing efficiency.

How to get apparent power?

Calculate it by multiplying Root Mean Square (RMS) Voltage by RMS Current (S = V × I), or using the power triangle: S = √(P² + Q²).
