EngineeringPaper.xyz — The Complete Guide: An Engineering Calculation Sheet With Units in the Browser
EngineeringPaper.xyz is a browser app for writing engineering calculations in the style of Mathcad. You type formulas with units, and it checks that they are consistent and converts them automatically. The calculation runs locally in the browser, and you can save a file or create a link to share it.
