CalcIT

CalcIT is a software that provides an impressive interface that is easy to read with large, color-coordinated buttons, and mode indicators for degrees/radians/gradients and decimal/hex/binary modes. The software includes the usual scientific and memory buttons and supports multiple levels of nested parentheses.

CalcIT also provides a variety of quick numeric conversions between the English and metric systems, enabling seamless conversions between different measuring systems.

The software also has a fractions mode that allows you to work directly in fractions rather than decimal, which is particularly useful for individuals who work with recipes or woodworking designs.

In terms of customization, the display is customizable in three ways. First, many of the keys have keyboard shortcuts, which the user can display above the keys. The remaining keys can be activated with their keyboard counterparts, so users can use CalcIT without the mouse.
