Features and Screenshots (Linux)


Main window When determining conversions, you first select from a long list of subjects, including ones for area, charge, temperature, mass, density, and thermal conductance. You then choose your source and desired units, such as feet to centimeters. After that, you simply type in a specific number, and this application will convert it to your desired unit in mere seconds.
Search for units and categories Type in the unit or category name. As you type, Unit Converter will show all possible matches. Select a search result and click on the "Go" button to jump to that unit in the main window.
Add or remove custom units Unit Converter converts almost every unit of measurement under the sun into other units. However, if you find something missing, add can your own categories and units to the program
Hide categories in main window If you don't regularly work with, say, viscosity, you can remove it from the main window.
Set permissions After downloading the binary file, you may need to set proper permissions to run the program. Right click on the file, and select "Properties". In the properties dialog box, select the "Permissions" tab. Then check the box that says "Allow executing file as program."
