KVA Converter

About This Tool

The kva converter computes real power (kW) and reactive power (kVAR) from the input apparent power (kVA) and power factor. It is a domain-focused calculator for electrical engineers, electricians, and facility managers who size generators, transformers, or conduct load analysis. It supports single- and multi-phase systems by applying P = S × PF and Q = S × sqrt(1 − PF^2).
Conceptually, it treats S as the total magnitude of apparent power and PF as the cosine of the phase angle. With PF provided, P and Q are determined; PF omitted defaults to 1, yielding P = S and Q = 0. Validation ensures S ≥ 0 and PF ∈ [0,1].
Key differentiators include immediate results for both P and Q from minimal inputs, clear numeric outputs formatted to two decimals, and robust validation. It does not perform voltage, current, or efficiency calculations, making it straightforward for planning tasks and documentation.
Use cases include rating motors or generators, verifying loads during commissioning, and comparing equipment options during procurement. The tool aids engineers, technicians, and energy managers in communicating load requirements and ensuring compliance with electrical design standards.
