Kilovolt-amperes (kVA) and volt-amperes (VA) both measure apparent power in electrical systems — kVA is simply the larger unit, equal to 1,000 VA. Enter your Apparent Power in kVA into the kVA to VA Calculator to get the equivalent value in VA, along with the conversion factor used.

To convert kVA to VA, multiply the kilovolt-ampere value by 1,000. The formula is: S(VA) = S(kVA) × 1,000. For example, 5 kVA equals 5,000 VA.
Both kVA and VA measure apparent power, but kVA is 1,000 times larger than VA. kVA (kilovolt-amperes) is typically used for larger electrical systems, while VA (volt-amperes) is used for smaller applications.
Apparent power is the total power supplied to an electrical circuit, measured in volt-amperes (VA) or kilovolt-amperes (kVA). It represents the product of voltage and current, including both real power and reactive power components.
This conversion is essential for electrical engineers and technicians when sizing equipment, calculating power requirements, and ensuring proper electrical system design. Different applications may require values in different units.
There are exactly 1,000 VA in 1 kVA. This is a fixed conversion factor since 'kilo' means 1,000, so 1 kVA = 1,000 VA.
Transformers, generators, UPS systems, and large electrical motors commonly use kVA ratings. These ratings help determine the apparent power capacity of electrical equipment.
No, kVA and kW are different. kVA measures apparent power while kW measures real power. The relationship depends on the power factor: kW = kVA × power factor.
