kW to kVA

Kw to kva power calculator helps you to convert kw to kva electrical power. To covert kw to kva, you must know about power factor (efficiency). Here we provide you simple method to convert electrical power kw to kva. You just need to enter the kw value and power factor value and click on calculate.


Kilowatts measuring unit for electrical energy. It is derived from watts, watts use to measure small electrical energy. Kilowatts are used to measure high electrical energy. One kilowatt is equal to one thousand watts, kilowatt has one thousand times more power than a watt. All the modern equipment and gadgets are used to measure in kilowatts.

Kilowatt (kW) is used to measure the real power of an electrical system while using it. 


kVA stands for kilovolt ampere. Kilovolt ampere helps you to find the overall power used by the electrical system. It is a combination of real power and wasted power of an electrical system.

Power Factor:

Power factor is the ratio between actual power and apparent power. It is a measure between 0 to 1.

Frequently asked questions:

How to convert kW to kVA?

The conversion of kW to kva is very simple. To convert you need to divide the kw value with its power factor value.

kW to kVA conversion formula:

kVA = kw / PF

kW = kilowatts.

kVA = kilovolt ampere.

PF = Power factor.


If an AC has 22kW power and its power factor of 0.80 then find the kVA? We have kW = 22kW; PF = 0.80; kVA = ?

kW to kVA conversion formula:

kVA = kw / PF

kVA = 22 / 0.80

kVA = 27.5
