Handy unit conversion application.
Unit Converter Pro is a handy utility for students, teachers, and practitioners in engineering, physics, sciences, and technical subjects. It can quickly convert more than 1500 different units in 79 categories.
It contains the most important conversion factors for length, area, volume, mass, force, energy, temperature, and time units. But it provides many high-specialized units and categories, too.

Note: At this moment, the difference between Pro and Pro Plus versions is minimal. Both contain the same amount of units and categories. In contrast to Pro Plus, the Pro version has visible only the most common categories and units by default. The rest can be made visible by pressing the More… button.
