How to convert conductivity to resistivity?

Electrical resistivity (ER) is reciprocal to conductivity (EC) and results can be easily recalculated using formula EC=1/ER or vice versa ER=1/EC. Electrical resistivity is more convenient to use on non-saline soils, where conductivity can be mSm/m, while resitivity measures in 102-103 Ohm m range. 1000 Ohm m equals 1 mSm/m. You can find more conversions to ppm, TDS, grains of salt in this flyer.

DIY: Setup Zotero - free open source publication and citation manager

Zotero [zoh-TAIR-oh] is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources. It lives right where you do your research — in the web browser itself. You can use it to quickly grab and re-use citation from our public library “Soil Electrical Geophysics”.






A personal research assistant!

Zotero is the only research tool that automatically senses content, allowing you to add it to your personal library with a single click. Whether you're searching for a preprint on arXiv.org, a journal article from JSTOR, a news story from the New York Times, or a book from university’s or public library catalog, Zotero has you covered with support for thousands of sites.

  • Grab your research with a single click.
  • Store it privately or share with collaborators.
  • Select multiple sources and insert formatted reference list in your paper/report while writing it (MS Word plugin).
  • Store anything:

Zotero collects all your research in a single, searchable interface. You can add PDFs, images, audio and video files, snapshots of web pages, and really anything else. Zotero automatically indexes the full-text content of your library, enabling you to find exactly what you're looking for with just a few keystrokes.
