Calcpad is modern, powerful and easy to use, free and open source software for engineering calculations. With its double windowed interface you can write your equations and report contents on the left and immediately see the formatted results on the right side. The output can be exported in native MS Word docx files with equations, as ell as html and pdf.

It uses a simple and easy to learn programming language that natively support units of measurement. You can use conditions and loops to branch not only the calculation path, but also the report contents, which is a unique feature to Calcpad.

It integrates Html, CSS and JS/JQuery for the creation of breath-taking dynamic output and animations. And also parametric vector drawings by using SVG. The geometry can depend on certain input values and calculation results and update after each re-calculation.
