About ConversionGenie
Fast, honest, globally useful.
ConversionGenie is a free, lightweight unit conversion tool built for everyday use — whether you're cooking, travelling, working, or just curious.
The goal is simple: give anyone in the world instant, accurate conversions with no friction. No account. No sign-up. No ads blocking the result. Just type a number and get an answer.
What we cover
Weight, length, area, temperature, speed, time, currency and data storage — with more categories planned. Each converter shows a primary result plus secondary conversions so you get context at a glance.
Privacy-first philosophy
ConversionGenie doesn't store anything on a server. Favourites and recently used conversions live only in your browser's localStorage — private to your device, cleared when you choose.
Part of the GenieSuite
ConversionGenie is a sibling tool to ProfitGenie.pro, a business and profit calculator platform. Both tools share the same design philosophy: fast, calm, and useful for anyone, anywhere.
