Plasma Formulary is an interactive, Web-based application that provides a comfortable access to evaluating, comparing, and plotting of a multitude of different plasma and atomic physics parameters, grouped by the unit dimensions. A special attention is devoted to the Stark broadening which is calculated with a good accuracy for transitions between degenerate atomic levels. The list of the entities calculated encompasses over one hundred entries and is easily expandable.

The application is built using open-source components and is compatible with a majority of modern browsers.
