kVA to Watts Calculator
Convert apparent kVA to real watts: W = kVA × PF × 1000. Default 3 kVA at PF 0.9 gives 2700 W. Informational only.

How to convert kVA to watts
- Enter kVA from a nameplate or calculation.
- Enter power factor.
- Read watts. The engine multiplies by 1000 after PF.
- Energy cost uses kWh on the electricity cost page. Nothing is uploaded.
kVA to watts
W = kVA × PF × 1000
| Apparent | kVA input |
|---|---|
| Real | Watts output |
| PF | Scales apparent down to real |
| Default | 3 kVA × 0.9 × 1000 = 2700 W |
| kW view | Same as 2.7 kW in the example |
| Approval | Informational. Not billing. |
Three-factor product
W = kVA × PF × 1000. Three kVA at PF 0.9 is 2700 W real.
kW intermediate
kW = kVA × PF is the same as dividing watts by 1000. The kVA to kW page shows kilowatts directly.
Electricity cost
Turn watts and hours into cost on electricity cost with your $/kWh rate.
Watts to kVA
Start from watts on watts to kVA when that is the given value.
Limits
Single PF number.

How many watts is 3 kVA at PF 0.9?
2700 W. Multiply 3 × 0.9 × 1000.
Why multiply by 1000?
kVA uses kilo scale; watts use base units.
Can I use this for motor heat loss?
It gives real watts from apparent kVA and PF, not a full loss breakdown.
Where is kVA to kW?
That page returns kilowatts instead of watts. Multiply its kW by 1000 mentally or use this URL.
Does PF affect kVA?
PF converts between kVA and watts. kVA itself does not include PF until you multiply.
