kVA to kW Calculator – Convert Apparent Power to Real Power

When dealing with electrical systems—whether you’re sizing a generator or calculating industrial loads—knowing the real power (kW) from the apparent power (kVA) is crucial. This is where the kVA to kW Calculator on TheVoltageHub comes into play.

It’s a quick, accurate, and free online tool that eliminates manual conversions and errors.

kVA to kW Calculator

Convert apparent power (kVA) into real power (kW) using power factor.

Power (kVA): Power Factor (0 to 1): Calculate Reset

Result: 0 kW

📘 What is the Difference Between kVA and kW?

Let’s keep it simple:

• kVA (Kilovolt-Amperes): Apparent Power
• kW (Kilowatts): Real or usable power

The link between them is the Power Factor (PF)—a value between 0 and 1 that measures efficiency.

Formula:

kW = kVA × Power Factor

For example, if you enter 100 kVA with a power factor of 0.8, you’ll get:

kW = 100 × 0.8 = 80 kW

Instant, simple, and error-free.

You don’t need to be an electrical engineer to use this. Just:

1. Enter your kVA
2. Add the Power Factor
3. Click Calculate
4. Instantly get your result in kilowatts

🧠 Understanding the Power Factor

The power factor varies based on the load type:

• Resistive loads (heaters, lights): ~1.0
• Inductive loads (motors, compressors): ~0.8 or lower

Knowing this helps you get more accurate results.
