kVA = kW / Power Factor
In 3 phase projects, convert kW to kVA first so downstream current, breaker, and cable calculations are based on apparent power.
Example
- 10 kW at PF 0.80 -> 12.5 kVA (3-phase workflow)
- 45 kW at PF 0.90 -> 50.0 kVA (3-phase workflow)
FAQ
What is the formula for kW to kVA in 3 phase workflow?
Use kVA = kW / PF, then continue with kVA to amps and protection sizing tools.
Why is power factor required?
Power factor defines the relation between real and apparent power, so it is essential for accurate conversion.
What power factor should I use?
Use measured PF when available; otherwise apply an engineering estimate based on your load profile.
