📖About This App

Unit Converter covers 12 everyday categories — Length, Weight, Temperature, Volume, Area, Speed, Time, Data, Pressure, Energy, Power and Angle — with a simple From/To layout, adjustable precision, and search to jump straight to the unit you need. Mark units as favorites or pull them from Recent for quick access. An optional Conversion Insights panel goes beyond the plain result with the formula used, a step-by-step calculation explanation, a reverse conversion, scientific notation and related units — unlock it for free by watching a short video, spend a pass, or get unlimited access with Pro. The app also bundles a small set of everyday device tools — Compass, Battery status, Metal Detector and Flashlight — in its Tools tab, so you don't need a separate app for them. Every conversion runs on-device, so the app works fully offline with no data sent anywhere to compute a result. Unit Converter is available in 14 languages, with a free version supported by ads and an optional Pro upgrade for unlimited Conversion Insights and an ad-free experience.
