Unit Converter Offline

Unit Converter Offline is a fast, clean converter for everyday units. Type a number and every other unit in the category updates at once. It covers length, area, volume, mass, temperature (Celsius, Fahrenheit, Kelvin and Rankine), speed, time, data storage, pressure and energy.

Choose the From and To units, or tap any unit in the list to make it the target. A swap button reverses the direction, and one tap copies the result or any row. Mark favourite units, and recently used units appear near the top. The app remembers your last category and units.

Conversions are calculated on your device, so the converter works without an internet connection. There is no account and no sign-in. The app shows ads served by Google AdMob.
