From the developer: "UniCvt is a configurable and versatile unit conversion program that allows quick and easy conversion between units of measurement. The interface is intuitive and user friendly, enabling even first-time users to convert from one unit to another without a hassle. It needs minimum keystrokes to get the conversion. UniCvt should answer the practical needs for engineers, scientists, students and anyone who needs to perform unit conversions regularly. A high-performance math expression evaluator is built-in. The default database provided with UniCvt can convert over 350 units in 17 categories. Updates to the default database are made available, periodically, on the UniCvt website. UniCvt is totally customizable. You can add your own custom units or your own custom categories! Conversion results can be viewed in different formats. It also displays a list of common physical constants and provides the ability to add your own constants."
