kW to kVA Calculation

Apparent Power
1.25kVA
Σ

Calculation Formula

S(kVA) = P(kW) / PF

To find kVA (Apparent Power), divide the power in kW by the power factor.

Typical Reference Values

1 kW Load
1.25 kVA @ 0.8 PF
10 kW Motor
12.5 kVA @ 0.8 PF
50 kW Furnace
55.6 kVA @ 0.9 PF
100 kW Site
142.9 kVA @ 0.7 PF
