Calculator Plus is a much expanded against the system, free Microsoft calculator that allows not only to perform various calculations but also conversion between different units of measurement and currencies. Compared to other calculators, the calculation possibilities of the Plus Calculator are quite modest. It does not contain trigonometric functions, defined constants such as "pi" or "e", but only buttons to perform basic mathematical operations.

The advantage of this program, however, are the mentioned possibilities of converting values saved in different units of measurement. There is a huge number of them to choose from, and the Polish nomenclature allows you to easily carry out the desired operation.
