kW = kVA × PFWithin this model
Non-negative real power consumed by a load, with true power factor greater than 0 and at most 1. Does not model export, transient demand or equipment capacity.
What the numbers mean.
Power factor is the ratio of real power to apparent power. Multiplication gives kW from kVA; division gives kVA from kW. A single power-factor value cannot establish whether a generator, UPS or transformer can support a particular load.
Formula reference: Schneider Electric · Electrical Installation Guide ↗A worked example
10 kVA × 0.8 = 8 kW. Conversely, 8 kW ÷ 0.8 = 10 kVA.
