ExpressionsCalculator is a multifunction scientific calculator offering
a wide range of features specific for anyone looking from basic to advanced calculations. It is an **ideal tool
optimised for high-school and university students,
chemists, engineers, mathematicians and physicists**. ExpressionsCalculator is revolutionary
in the way it helps you solve problems by providing you, in addition to all the basic features of a calculator,
a rich sample of natural constants, a **large database of commonly used formulae in mathematics, physics and chemistry**,
all this in a fully embedded and aware SI (MKSA), imperial (foot, pound, …) and astronomical (ly, parsec, …) **units context**.
Hence, in ExpressionsCalculator a physical quantity has a unit. When you perform calculations, units are always taken care of and
automatically simplified to provide the most sensible result. Derived units such as Newton, Joule, etc. are handled.
Conversions from one unit to others are automatic.
In addition, ExpressionsCalculator can also handle multi-dimensional vectorial quantities.
