Purpose
Calculeaf is a free browser-based engineering calculation software, mainly aimed at the creation and use of engineering calculation worksheets. It is positioned as an alternative to Mathcad, suitable for structural verification, mechanical calculations, unit conversions, design records, and shareable worksheets that need to show the calculation process and results.
Main Capabilities
- Calculations with units: Supports the SI, USCS, and CGS unit systems, including unit conversions and derived units.
- Document-style worksheets: Can combine mathematical regions, text, charts, images, headers, and printable calculation pages in the same document.
- Reusable calculations: Can save worksheets, create templates and code snippets, and share calculation sheet copies.
- Engineering functions: Provides constants, statistical functions, matrices, vectors, comparisons, and iterative calculations.
- Charts and output: Can add line charts, area charts, and scatter plots directly next to the equations that generate them.
- AI-assisted writing: Can draft calculation content based on prompts and run a worksheet overview to check the flow.
- Mathcad import: Supports importing Mathcad Prime (.mcdx) and Mathcad 15 (.xmcd) files, converting their regions, formulas, and units into editable Calculeaf worksheets.
How to Use
Calculeaf runs in the browser, with no installation, no license fee, and no registration required for trial use. Users can open a blank worksheet to start calculating, or open an example worksheet. Mathematical regions and dropdown regions in the main body of the worksheet are evaluated from top to bottom and, within the same row, from left to right; names defined using := must be located above the row where they are used. It is not a spreadsheet, but rather closer to a calculation sheet, with equations and explanations displayed side by side on the same page.
Applicable Scenarios
Suitable for structural checks, mechanical calculations, unit conversions, design descriptions, and shareable worksheets that need to explain the mathematical process and results.
Limitations
The materials do not provide specific information about platform compatibility, browser version requirements, collaboration features, data storage, or privacy policy, and none is currently provided.
