## What is VA to kW calculator

To convert volt-amps (VA) to kilowatts (kW), you need to know the power factor (PF) of the load. The formula for converting VA to kW is:

kW = (VA x PF) / 1000

Multiply the apparent power in volt-amps by the power factor, and then divide the result by 1000 to obtain the real power in kilowatts.

For example, if you have an electrical load with an apparent power of 5000 VA and a power factor of 0.9, you can calculate the real power in kilowatts as follows:

kW = (5000 VA x 0.9) / 1000 kW = 4.5 kW

In this example, the load has a real power consumption of approximately 4.5 kilowatts.

Please note that volt-amps (VA) represent apparent power, which is the combination of real power and reactive power. The power factor (PF) represents the ratio of real power to apparent power and indicates how effectively electrical power is being utilized. It is important to consider the power factor when converting VA to kW, as the actual power consumption may vary depending on the load's power factor.

## VA to kW calculation

The real power P in kilowatts (kW) is equal to the apparent power S in volt-amps (VA), times the power factor PF divided by 1000:

P(kW) =  S(VA) × PF / 1000

## VA to kW calculator Example

Apparent Power (VA) Power Factor Real Power (kW)
1000 0.8 0.8
1500 0.9 1.35
2000 0.95 1.9
2500 0.85 2.125
3000 0.75 2.25
3500 0.92 3.22
4000 0.98 3.92

To calculate the real power (kW) from VA and power factor, you can use the formula:

Real Power (kW) = Apparent Power (VA) * Power Factor

For example, if you have an apparent power of 1000 VA with a power factor of 0.8, you would calculate the real power as follows:

Real Power (kW) = 1000 VA * 0.8 Real Power (kW) = 800 watts or 0.8 kW
