Volt-amps and kilovolt-amps both measure the apparent power in an electrical circuit. Volt-amps are usually express as VA and kilovolt-amps are usually expressed as kVA. This is the formula to convert VA to kVA.

The apparent power S in kilovolt-amps (kVA) is equal to the apparent power S in volt-amps (VA), divided by 1000:

kVA = VA ÷ 1,000
