Frequently Asked Questions
What is apparent power, and what units does this converter use?
Apparent power is measured in volt-amperes (VA, kVA, MVA) — the total combined power in an AC circuit, comprising both real (working) and reactive power.
What's the difference between apparent power and real power?
Real power (watts) is the power that actually does useful work, while apparent power (VA) is the vector combination of real and reactive power — apparent power is always equal to or greater than real power.
Why are generators and UPS systems rated in kVA instead of kW?
Manufacturers rate equipment in kVA because that reflects the actual current-handling capacity needed, regardless of the load's power factor — the real power (kW) delivered depends on the connected load's power factor.
How do I convert kVA to kW?
Multiply kVA by the power factor (a value between 0 and 1) to get kW. For example, 10 kVA at a 0.8 power factor equals 8 kW.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.
Is this useful for sizing a generator or UPS?
Yes — comparing your equipment's kVA rating against your load's actual power draw is a key step in properly sizing backup power systems.
How many VA are in a kVA?
1,000 VA equal one kVA.
What is a typical power factor for household equipment?
Many household devices have power factors between 0.7 and 0.95, though resistive loads like heaters can be close to 1.0 — check the specific device's rating for accuracy.
Is apparent power relevant for residential electricity billing?
Most residential customers are billed based on real power (kWh), but commercial/industrial customers are sometimes billed with power-factor-related charges tied to apparent power.
