A Mathcad alternative for engineering calculations

CalcStamp keeps what engineers like about Mathcad - calculations that read like hand calcs, with units - and runs in any browser, on Windows, Mac or a tablet.

• Type it the Mathcad way: L := 24 ft, M.u := w*L^2/8, Greek letters, subscripts and functions of your own.
• Every value substituted automatically - no switching on explicit calculation line by line.
• Converts Mathcad worksheets with AI into live sheets, each result checked against Mathcad's, and Excel, Word and PDF calcs too.
• Units carried and checked through every line, and results shown in the unit you ask for.
• Built for engineering work: tables, an Excel-style spreadsheet, load diagrams, parametric sketches, solving, calculus and matrices.
• Prints a clean calculation sheet with your title block, ready to check and stamp.
