Convert PLM to another file type
To convert PLM files to another format, you need ALOHA or other Data software.
Convert a file to PLM
To convert other file formats to the "Plume Modeling File" file type, you need software like ALOHA or a similar tool.
About PLM files
The .PLM file extension is most commonly associated with Radiological Plume Model data files. These files are generated by specialized environmental hazard software such as ALOHA (Areal Locations of Hazardous Atmospheres) or Hotspot Health Physics Codes. They store chemical release data, atmospheric dispersion metrics, and toxic footprint calculations. A major disadvantage of this format is its proprietary, closed nature. Standard GIS or spreadsheet software cannot directly read .PLM files, trapping your critical environmental data inside the original simulation program. To analyze this data elsewhere, users typically need to export the results to KML for mapping or CSV for data analysis. Beyond plume models, .PLM files can also function as SD-Voice Playlist Files created by the SD Association for legacy portable audio devices. These playlists use specific internal encoding that modern media players reject, requiring conversion to standard M3U or PLS files. Finally, .PLM is historically used for PL/M Source Code (Programming Language for Microcomputers), an obsolete programming language developed by Gary Kildall. Standard online converters often fail with .PLM files because they cannot distinguish between binary environmental models, media playlists, and raw source code. Just drag and drop your file to convert.guru to identify the format, view its internal structure, and convert it when possible.
Convert.Guru analyzes your PLM file, detects the exact format, and lets you read the text inside.
If you want to convert PLM file to , you can use ALOHA or similar software from the "Radiological Plume Model Data" category. In the File menu, look for Save As… or Export….
To convert files to PLM, try ALOHA or another comparable tool in the "Radiological Plume Model Data" category.
The PLM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PLM converter.
