UnitConverter MIDlet provides easy unit conversion (length, volumes, etc.) on Nokia Series 40 mobile phones primarily, but is compatible with any J2ME CLCD-1.0 (or higher) device (basically all modern phones). It was developed using Nokia J2ME development tools together with Eclipse. Currently, only the Nokia Series 40 quick-access keys and 128x128 pixel display are supported; on other devices some keys may be cumbersome to access and the display layout look weird, but the software should work on most devices out there.
