How to convert kVA to kW

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

kVA to kW calculation formula

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

P(kW) =  S(kVA) × PF

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

kilowatts = kilovolt-amps × PF

or

kW = kVA × PF

Example 1

What is the real power in kilowatts when the apparent power is 4 kVA and the power factor is 0.8?

Solution:

P = 4kVA × 0.8 = 3.2kW

Therefore, the real power in this example is 3.2 kilowatts.:

It's important to note that the power factor is a measure of the efficiency of an electrical system, and it is defined as the ratio of real power to apparent power. Real power is the power that is actually used to do work, while apparent power is the power that is supplied to an electrical system. A power factor of 1 indicates that all of the apparent power is being used to do work, while a power factor less than 1 indicates that some of the apparent power is being lost due to electrical inefficiencies.:

Example 2

What is the real power in kilowatts when the apparent power is 5 kVA and the power factor is 0.8?

Solution:

P = 5kVA × 0.8 = 4kW

Example 3

What is the real power in kilowatts when the apparent power is 10 kVA and the power factor is 0.8?

Solution:

P = 10kVA × 0.8 = 8kW

Example 4

What is the real power in kilowatts when the apparent power is 50 kVA and the power factor is 0.8?

Solution:

P = 50kVA × 0.8 = 40kW

Example 5

What is the real power in kilowatts when the apparent power is 100 kVA and the power factor is 0.8?

Solution:

P = 100kVA × 0.8 = 80kW
