gensymb

The gensymb extension implements the gensymb style package from LaTeX. It provides a number of macros for unit notation. See the CTAN page for more information and documentation for gensymb.

Note that the mathjax-tex font (the original default font in v2 and v3) does not include several of these characters, so the output will depend on the system fonts available to your reader, and will vary from reader to reader.

This package is not autoloaded, so you must request it explicitly if you want to use it. To load the gensymb extension, add '[tex]/gensymb' to the load array of the loader block of your MathJax configuration, and add 'gensymb' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/gensymb']},
  tex: {packages: {'[+]': ['gensymb']}}
};

You can configure the autoload extension to load gensymb via

window.MathJax = {
  tex: {
    autoload: {
      gensymb: ['celsius', 'degree', 'micro', 'ohm', 'perthousand']
    }
  }
};

Alternatively, use \require{gensymb} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
