Convert units of measurement easily with Converter for Android. The black background with white text is easy on the eyes, and the menu is simple to navigate. Choose from a variety of measurements, such as length, temperature, weight and speed, and then you'll see the option to select from multiple units. The app uses the calculator interface and features large-size numbers and buttons, so you can quickly type numerals. There's a free version of Converter, which features ads, and the paid version removes advertisements, although, the ads are displayed at the bottom of the app and aren't very noticable. The Preferences menu lets you change settings to your liking, including the number of decimal places displayed.
