About Kilowatts to Amps

Kilowatts to Amps is a free, fast, and accurate online converter built for anyone who needs to convert between kilowatts and amps — from electricians sizing circuit breakers to homeowners understanding their electrical panel. We support DC, single-phase AC, and three-phase AC circuits with instant, reliable results.

Our Story

Kilowatts to Amps was born out of a real-world need: quickly and accurately converting between kilowatts and amperes shouldn't require flipping through textbooks or hunting through cluttered, ad-laden websites. Yet most online tools were either oversimplified — covering only DC — or buried behind confusing interfaces that didn't account for voltage, power factor, or circuit type.

We set out to build the most comprehensive kW-to-amps converter on the web — one that handles DC, single-phase AC, and three-phase AC circuits, supports a wide range of voltages, and explains the formulas behind every result. All wrapped in a clean, modern interface that delivers answers instantly.
