ARWIVO Convert units

Convert length, area, volume, mass, temperature, speed and duration. Results update as you type. Swap units, copy results with units or share them. Favourite pairs and local history make repeated calculations easier. Core functions work offline without an account. Settings and entries stay on your device. Removal requires confirmation and can be undone during the same session. Use a comma or dot as the decimal mark, without thousands separators. US liquid and imperial gallons are separate units. Pounds and ounces use the avoirdupois system. Temperatures below 0 K are rejected. Display up to 12 significant digits; ≈ marks rounding. This tool does not replace a measuring instrument or technical standards. No currencies, nominal thread sizes or mass-to-volume conversions without density. Includes a small Google AdMob banner. Ads need internet; the converter does not.

First release: 7 unit categories, offline conversion, favourite pairs and local result history. English, Polish and German.
