# VA to watts calculator

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

## What is VA to watts calculator

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

Watts (W) = VA x PF

Simply multiply the apparent power in volt-amps by the power factor to obtain the real power in watts.

For example, if you have an electrical load with an apparent power of 1000 VA and a power factor of 0.8, you can calculate the real power in watts as follows:

Watts (W) = 1000 VA x 0.8 Watts (W) = 800 W

In this example, the load has a real power consumption of 800 watts.

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 watts, as the actual power consumption may vary depending on the load's power factor.

## VA to watts calculation

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

*P*_{(W)} = *S*_{(VA)} × *PF*

## VA to watts calculator Example

To convert volt-amps (VA) to watts (W), you need to know the power factor (PF) of the circuit. The formula to calculate watts from VA and power factor is:

W = VA * PF

Here's an example that demonstrates using the VA to watts formula:

Let's assume you have a circuit with an apparent power of 1000 VA and a power factor of 0.8. We want to calculate the power consumption in watts.

Using the VA to watts formula: W = VA * PF W = 1000 VA * 0.8 W = 800 watts

Therefore, the power consumption of the circuit is 800 watts.

This calculation takes into account the power factor, which represents the efficiency or quality of the electrical system. A power factor less than 1 indicates the presence of reactive power. It's important to note that if the power factor is not provided, you cannot directly convert VA to watts without additional information.
