kW to VA Calculator

Convert kilowatts (kW) to volt-amps (VA) using power factor. Calculate the apparent power in VA for UPS and power supply sizing.

kW

APPARENT POWER

5,882 VA

IN kVA

5.88 kVA

FORMULA

VA = (kWΓ—1000)/PF

POWER FACTOR

0.85

πŸ’‘ How to Convert kW to VA

Formula

VA = (kW Γ— 1,000) / PF

Example: 5 kW at PF = 0.85 β†’ VA = 5,000 / 0.85 = 5,882 VA

UPS systems are rated in VA. To ensure your UPS can handle your load, convert the load's real power (kW) to apparent power (VA).

5 kW Γ· 0.85 PF = 5,882 VA. Always size your UPS based on VA, not watts.
