Frequently Asked Questions
How do I calculate kVA from kW and power factor?
kVA = kW ÷ Power Factor. Example: 1 kW at 0.85 PF = 1.18 kVA.
What is the typical power factor for motors?
Motors typically have 0.8–0.9 PF. Resistive loads have 1.0 PF.
Does power factor affect kW to kVA conversion?
Yes, lower PF requires higher kVA for the same kW.
What is the difference between kW and kVA?
kW is real power doing useful work; kVA is apparent power including reactive components. Relationship: kW = kVA × Power Factor.
What is a good power factor value?
Industrial targets are typically 0.85–0.95. Values below 0.85 may incur utility penalties.
What is a kW to kVA converter?
A kW to kVA converter is a tool that converts real power (kW) to apparent power (kVA) using power factor. It helps engineers size generators, transformers, and electrical systems correctly.
