KWCalc was created with one simple goal: to make power and energy calculations easy, accurate, and accessible for everyone. Whether you are a homeowner checking the running cost of an appliance, an engineer planning loads, or a student learning electrical basics, our tools help you quickly find the answers you need.
We specialize in electrical calculators and energy planning tools, including kW to Amps conversions, generator sizing, solar planning, and electricity cost estimations. Our focus is on simplicity, accuracy, and real-world usefulness.
With the release of the Electric Bill Estimator Chrome Extension, we’ve made it even easier to calculate energy costs directly while browsing shopping websites, product pages, or online reviews. You can instantly know how much a device will cost to run, the current it will draw, and even the generator or solar power requirements.
Our mission is to save you time, reduce guesswork, and help you make smarter energy decisions — whether for your home, business, or studies.
