**How to convert from kVA to Watts in 1 step only:**

**Step 1:**

To convert from kVA to Watts you must multiply the kVA by the power factor (FP) and then by 1000. If you do not know the power factor of the load, you can consult the most common fp on this website: https://www.calculatorsconversion.com/es/factor-de-power-motores-construcciones-electrodomesticos/

For example, an electric motor has a power of 45kVA, with a power factor of 0.88, to convert to Watts the power that is in kVA must be multiplied 45kVA by 0.88 and then by 1000, as follows 45kVAx0.88 × 1000 = 39600Watts.

**Examples of conversions from kVA to Watts, three-phase, biphasic and monophasic:**

**Example 1:**

An extractor of a tunnel has a power of 34kVA, with a power factor of 0.81, how many Watts does this motor have?

Answer: // To know the answer you must multiply 34kVA by the power factor and then by a thousand, as follows: 34 × 0.81 × 1000 = 27540Watts.

**Example 2:**

An industrial laser printer has a power of 2.7kVA, with a power factor of 0.92, how many Watts does the printer have?

Answer: // The first thing to do is multiply the 2.7kVA by the power factor and then by 1000, the result will be: 2.7 × 0.92 × 1000 = 2484Watts, as you can see the higher the factor of higher power will be Watts, remember that the power factor can not be greater than 1.

**Example 3:**

An industrial equipment has a power of 18.3kVA, with a power factor of 0.86, how many Watts will the equipment have?

Answer: // To know the kVA, the Watts must be divided between the multiplication of the power factor and 1000, giving as a result: 18.3 × 0.88 × 1000 = 15738 Watts.
