ScalarCalc

A calculator is one of the most simple pieces of software. Calculators can be integrated as parts of an operating system or can be developed as standalone apps. Usually, the integrated tools are less likely to have extensive coverage of mathematical calculations, while the purposely designed calculator is more capable of performing a large number of processes. One of those apps is ScalarCalc, and it can be very helpful.

The GUI is composed of a plain window where multiple tabs can be loaded. Note that the tabs cannot be all displayed at once, but a toolbar is created at the bottom of the interface that provides a quick selection.

A permanent tab (can be minimized though) is called "Storage," from there you can save a number of results, clear, copy as well as print them. There is a small screen where you can see what is loaded in the clipboard.

ScalarCalc has a decent unit catalog, and almost any element provides a combo menu with units of measure. For example, go to ''Unit-Tables'' and select ''Speed'' a table with groups from both imperial and metric system are listed and compared.

The app can also perform necessary calculations as well as more complicated ones. You can perform calculations using physics formulas, advanced math and even geometry models.

To sum it up, ScalarCalc is a unit converter and unit calculator that solves real equations. A great educational tool and sturdy enough for any workplace. As a small note, this app can be used by novice users but there are limits, so in order to fully exploit it one may need to possess a more significant package of mathematical notions.
