kVA to watts calculator FullScreen

Convert apparent power in kilovolt-amperes (kVA) to real power in watts (W). Ideal for understanding the actual power consumption of electrical systems and equipment. Obtain an estimation of watts from kVA using this convenient online tool.

Enter kilovolt-amps: kVA
Enter power factor:  
Result in watts: W


What is kVA to watts calculator

To convert kilovolt-amps (kVA) to watts (W), you need to know the power factor (PF) of the load. The formula for converting kVA to watts is:

Watts (W) = kVA x 1000 x Power Factor (PF)

Multiply the apparent power (kVA) by 1000 and then multiply that result by the power factor (PF) to obtain the power consumption in watts.

For example, if you have a load with an apparent power of 5 kVA and a power factor of 0.8, you can calculate the power consumption in watts as follows:

Watts (W) = 5 kVA x 1000 x 0.8 Watts (W) = 4000 W

In this example, the load consumes 4000 watts of power.

It's worth noting that the power factor represents the ratio of real power to apparent power. It indicates how effectively electrical power is being used and can vary depending on the type of load. For loads with unknown or unspecified power factors, it is common to assume a power factor of 1 (unity) for simplicity or refer to specific device or system specifications for accurate power factor values.

kVA to watts calculation

The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P(W) =  1000 × S(kVA) × PF

kVA to watts calculator Example

To convert kilovolt-amps (kVA) to watts (W), you need to know the power factor (PF) of the electrical system. The formula to calculate watts from kVA and power factor is:

Watts (W) = kVA * 1000 * PF

Here's an example that demonstrates the calculation:

Let's assume you have a power factor of 0.9 and a kVA rating of 10 kVA.

Watts (W) = 10 kVA * 1000 * 0.9 = 9000 W

Therefore, the power in watts corresponding to a 10 kVA rating with a power factor of 0.9 would be 9000 watts.

Please note that the power factor represents the efficiency or quality of the electrical system. The power factor should be considered when converting between kVA and watts, as it affects the actual power output of the system.
