SunCALC (Scientific Calculator with Unit Support)

The Scientific UNit Calculator App combines the function of a spred sheet with the functions of a scientific calculator.

A unique feature of this App is the integrated possibility to convert between expressions given with different units. It does not only support the simple conversion like Inch to Meter "in ⇛ m" from one unit to the other like many other unit conversion Apps. It also supports the conversion of complex units like Inch per hour into Meter per Second "in/h ⇛ m/s".

Furthermore the conversion between currencies is supported. The currencies conversion rates are loaded from a web service provided by the EZB.

It is possible to enter conditional expressions.
