kVA to VA Calculator
Convert kilovolt-amps (kVA) to volt-amps (VA) by multiplying by 1,000. Useful for comparing UPS, inverter and transformer ratings listed in different units.
VOLT-AMPS
25,000 VA
FORMULA
VA = kVA × 1,000
MEGAVOLT-AMPS
0.025 MVA
💡 How to Convert kVA to VA
To convert kVA to VA, multiply the kilovolt-amps by 1,000. Both units measure apparent power, the product of voltage and current, so the conversion is a simple change of scale with no voltage or power factor involved.
kVA to VA formula
Example: 2 kVA × 1,000 = 2,000 VA
Worked examples
- Home inverter: a 0.6 kVA unit is 600 VA, the size usually sold as a "600 VA" inverter.
- Rack UPS: a 3 kVA UPS is 3,000 VA.
- Portable generator: a 7.5 kVA generator is 7,500 VA.

When you need VA rather than kVA
Smaller equipment such as desktop UPS units, inverters and control transformers is usually labelled in VA, while larger transformers and generators use kVA. Converting both to the same unit lets you compare them directly, or add up several loads to check they fit within one rating.
Going further: VA to watts and amps
A VA figure tells you how much current the equipment can carry, not how many watts it delivers. To find real power, multiply by the power factor with the VA to kW calculator. To find the current, divide by the voltage with the VA to amps calculator.
