kW to kVA calculator

kW to kVA calculator

Kilowatts (kW) to kilovolt-amps (kVA) conversion
Input real power in kilowatts(kw) and power factor(p.f) and click the Calculate button to obatin the apparent power (in kilovolt-amps)

Input kilowatts: kW
Input power factor:
Result (in kilovolt-amps): kVA






How to convert real power in kilowatts (kW) to apparent power in kilovolt-amps (kVA).

kW(kilowatts) to kVA(kilovolt-amps) conversion formula

S=The apparent power S in kilovolt-amps (kVA)
P=the real power P in kilowatts (kW)
P.F=the power factor PF:

S(kVA) =  P(kW) / PF

So that you can rewrite this formula as

kilovolt-amps = kilowatts / PF

or

kVA = kW / PF

Let's take one Example
Example #1
I want to Calculate the apparent power(in kilovolt-amps) where the real power is 5 kW and the Pf is 0.7?
Apply conversion formula:
S = 5kW / 0.7 = 7.14kVA
Example #2
I want to Calculate the apparent power(in kilovolt-amps) where the real power is 10 kW and the Pf is 0.8?
Apply conversion formula:
S = 10kW / 0.8 = 12.5kVA
What is KVA(kilovolt-ampere)
A kilovolt-ampere, a measurement used for the apparent power in a circuit, equal to the multiple of RMS(i.e root-mean-square )voltage and RMS(i.e root-mean-square ) current so that you can say that AC (AC) circuits.While voltage product by amperes is generally termed as ‘watts’.
