To convert from kilowatts (kW) to kilovolt-amperes (kVA), you need to know the power factor (PF) of the system. The relationship is:
\[
\text{kVA} = \frac{\text{kW}}{\text{Power Factor (PF)}}
\]
- **1 kW** is equal to **1 kVA** if the power factor (PF) is **1** (which happens in purely resistive loads, like heaters or incandescent light bulbs).
- If the power factor is less than 1 (e.g., for inductive loads like motors or transformers), the kVA will be higher than the kW. For example, if PF = 0.8, then:
\[
\text{kVA} = \frac{1 \, \text{kW}}{0.8} = 1.25 \, \text{kVA}
\]
So, the kVA value depends on the power factor of the system.
\[
\text{kVA} = \frac{\text{kW}}{\text{Power Factor (PF)}}
\]
