Kilowatts to kilovolt-amperes
Type a value in kW to get it in kVA instantly.
125kVA
That's 2.5× as big as a pole-mounted transformer, while a neighbourhood substation is 8× bigger.

What it means
How big a supply is that?
Watts, kilowatts and kvar depend on the power factor chosen above. Reference ratings are typical.
The math
How to convert kW to kVA
kW = kVA × PF and kvar = kVA × √(1 − PF²). The three form a right triangle: kVA² = kW² + kvar². The figures below use the power factor selected above.
Example: 100 kW = 125 kVA.
The watts, kilowatts and kvar below assume 0.8 (generator rating). Change it above and every number updates.
