What I do here

I write and check everything on this site: the kVA to amps calculator, the amps to kVA converter, the three-phase, generator and transformer tools, the printable chart and the methodology behind them. My background is in building practical web tools; my habit, learned the useful way, is to verify every published formula against the standard it comes from — in this case the electrical identities set out in IEEE and IEC publications and the National Electrical Code's approach to full-load current.

This site exists because a top-ranked converter for this exact calculation applies a power factor where none belongs, overstating currents by 25%. Checking that claim — and being able to prove it wrong in four lines — is the kind of verification I do before anything here is published. The proof is on the methodology page.
