Volt-amperes (VA) and kilovolt-amperes (kVA) are both units of apparent power used in electrical systems — kVA simply expresses the same value in thousands, making it easier to read for larger equipment ratings. Enter your Apparent Power in VA into the VA to kVA Calculator to get the equivalent kVA result rounded to three decimal places.
Apparent Power (kVA)
--
To convert VA to kVA, divide the apparent power in volt-amperes by 1,000. The formula is: kVA = VA ÷ 1,000. Since there are 1,000 volt-amperes in 1 kilovolt-ampere, this conversion is straightforward.
Volt-Amperes (VA) is the unit for apparent power in an electrical circuit. It represents the product of the root mean square (RMS) voltage and RMS current in an AC electrical system.
Kilovolt-Amperes (kVA) is a unit of apparent power equal to 1,000 volt-amperes. It's commonly used for rating electrical equipment like transformers, generators, and UPS systems where larger power ratings are involved.
kVA is used for convenience when dealing with large electrical systems because the numbers are more manageable. Instead of saying 50,000 VA, it's easier to say 50 kVA.
Yes, the conversion is always a simple division by 1,000. This is because kVA is defined as 1,000 times VA, making it a direct unit conversion without any other factors involved.
kVA measures apparent power while kW measures real power. kVA includes both real and reactive power components, whereas kW only represents the actual power consumed. The relationship is kW = kVA × power factor.
