I need a unit conversion application much like the dashboard widget called "Unit Converter". It could be a little more robust but really that is all I need. If it were a part of a calculator that would be fine. That way I could come up with the measurement I have and could convert it in one app. The conversions I need or liquid measures, area, distance/length, volume. I prefer a clean/not cluttered UI and easy to use (who doesn't). Can anyone suggest one from first hand experience?
