To convert **kVA (kilovolt-amperes)** to **kW (kilowatts)**, you need to know the **power factor (PF)** of the system:
$$
\text{kW} = \text{kVA} \times \text{Power Factor}
$$
* If the **power factor is 1.0** (purely resistive load), then:
$$
20 \text{ kVA} \times 1.0 = 20 \text{ kW}
$$
* If the **power factor is 0.8** (common for many industrial loads), then:
$$
20 \text{ kVA} \times 0.8 = 16 \text{ kW}
$$
So, the answer depends on the **power factor**. Do you know what the power factor is in your case?
