Conversion using the VA to KW Formula

How to Calculate KW from VA and power factor pf using AC current.

The Real Power P in Kilowatts kw is calculated as the apparent Power S in volt-amps VA times the Power factor pf, divided by 1000. Plug these values into the formula:

KW = VA × pf1000

For Example, let's convert 5500 VA with a power factor of 0.8 to kilowatts.

Real Power(P) = Apparent Power(S) × Power factor(pf)1000

or, P(KW) = 5500 VA × 0.81000

or, Kilowatts = 4.40000 KW

Frequently Asked Questions - FAQs for VA to KW Calculator

How is kVA calculated?

A calculate the kVA rating for a single-phase transformer, you'll need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1000: V × l ÷ 1000.

How to convert VA to volts?

A calculate voltage from volt-amps, simply divide the volt-amps by the current.

What is the VA in power?

A volt-ampere (VA) is the voltage times the current feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical power is measured in watts (W).

What is VA voltage?

The volt-ampere (VA) is the unit of measurement for apparent power (VA) in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes).

What is kW size?

A kilowatt is a 2 unit of power representing a rate of 2000 watts of electrical energy.
