# How to convert kW to kVA

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

### kW to kVA calculation formula

The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the power factor PF:

S(kVA) =  P(kW) / PF

So kilovolt-amps are equal to kilowatts divided by the power factor.

kilovolt-amps = kilowatts / PF

or

kVA = kW / PF

#### Example

What is the apparent power in kilovolt-amps when the real power is 3 kW and the power factor is 0.8?

Solution:

S = 3kW / 0.8 = 3.75kVA

### Kilowatt definition

One kilowatt (kW) is equal to 1000 watts (W):

1kW = 1000W

One kilowatt is defined as energy consumption of 1000 joules for 1 second:

1kW = 1000J / 1s

One kilowatt is equal to 1000000 milliwatts:

1kW = 1000000mW

### Kilovolt-ampere definition

kVA is kilo-volt-ampere. kVA is a unit of apparent power, which is electrical power unit.

1 kilo-volt-ampere is equal to 1000 volt-ampere:

1kVA = 1000VA

1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere:

1kVA = 1000⋅1V⋅1A
