UnitConvert

Convert everyday measurements wherever you are, with no internet connection required. Choose from eight categories: length, area, volume, mass, temperature, speed, time, and digital data. Enter a value and see its converted result update as you change the number or either unit. Swap source and target units in one tap, then copy the result or save a conversion for later. For a broader comparison, select up to eight target units and view them together. Copy one result or the selected results as plain text. Search unit names and abbreviations to find the measurement you need. Save frequently used unit pairs as favorites. Your saved pairs remain ready for another value, while recent records keep the input, result, units, category, and time together. Search records, remove an individual entry, clear history, or turn history recording off. Adjust displayed precision from two to ten decimal places, enable scientific notation for very large or small values, choose a default category, and personalize the display with a dark theme, larger text, or a one-hand category layout. Conversions and saved preferences stay on your device. The app does not require an account, network access, advertising, or external data. Temperature conversions account for the scale and offset between Celsius, Fahrenheit, and Kelvin.
