A more useful kind of appliance website
We build calculators that help you adapt a recipe, compare appliance capacity and understand energy use. Each tool combines a simple input form with an explanation of how the answer is obtained.
Transparent by design
You can inspect the formula, assumptions, examples and references on every calculator page. We distinguish reliable physical relationships from practical estimates. We do not claim laboratory testing, professional certification or institutional endorsement.
Built for your home
No account is needed. Calculations run in your browser. Choose your language and unit system independently, and use the result as a starting point for a better-informed decision.
