Converting amperes (amps) to kilovolt-amperes (kVA) is essential for understanding electrical power in various applications. The apparent power (S) in kVA can be calculated differently for single-phase and three-phase systems. In a single-phase system, the formula is: S(kVA) = I(A) × V(V) / 1,000, where I represents current in amps, and V represents voltage in volts. For three-phase systems, the formula becomes: S(kVA) = √3 × I(A) × V(V) / 1,000. Accurate conversion is crucial for sizing electrical equipment and ensuring system efficiency. Utilizing an online amps to kVA calculator can simplify this process, providing quick and precise results.
