To convert watts (W) to kilovolt-amperes (kVA), you need to know the power factor (PF) of the device. The formula is:
\[
\text{kVA} = \frac{\text{W}}{1000 \times \text{PF}}
\]
If we assume the power factor (PF) is 1 (which is typical for purely resistive loads like heaters or incandescent lights), then:
\[
\text{kVA} = \frac{1000}{1000 \times 1} = 1 \text{ kVA}
\]
So, if the power factor is 1, 1000 watts equals 1 kVA.
If the power factor is less than 1 (as it usually is for inductive loads like motors), the kVA will be higher than 1. For example, if the power factor is 0.8, the calculation would be:
\[
\text{kVA} = \frac{1000}{1000 \times 0.8} = 1.25 \text{ kVA}
\]
