VA to kW Calculator
Convert volt-amperes to real kilowatts: kW = VA × PF / 1000. Default 5000 VA at PF 0.88 gives 4.4 kW. Informational only.

How to convert VA to kW
- Enter apparent volt-amperes (not kVA).
- Enter power factor.
- Read kilowatts. Divide VA by 1000 after applying PF.
- For kVA inputs use kVA to kW instead. Nothing is uploaded.
VA to kW
kW = VA × PF / 1000
| VA | Apparent volt-amperes, not kilo |
|---|---|
| kW | Real power after PF |
| PF | Default 0.88 example |
| Default | 5000 VA × 0.88 / 1000 = 4.4 kW |
| kVA cousin | kVA pages use kilo prefix |
| Approval | Informational. Not a tariff. |
VA scale
kW = VA × PF / 1000. Five thousand VA is 5 kVA apparent; at PF 0.88 real power is 4.4 kW.
VA vs kVA
UPS labels often print VA. Divide by 1000 mentally for kVA or use this page directly when the plate lists VA.
From amps to VA
amps to volt-amps builds VA from V and I before PF conversion here.
kVA siblings
kVA to kW expects kilo-scaled apparent power.

What kW is 5000 VA at PF 0.88?
4.4 kW. Multiply 5000 × 0.88 and divide by 1000.
Should I use kVA instead of VA?
If the label says kVA, use kVA to kW. This page expects base VA.
Is VA the same as watts?
Only at PF = 1. Otherwise watts are smaller than VA for lagging loads.
Why default PF 0.88?
It is an example UPS or motor-like factor, not a measured default for your site.
Where do I convert VA to amps?
Try volt-amps to amps with voltage.
