Supported commands
fxTeX supports 1,302 LaTeX commands and 25 environments. Each one is
listed below under the kind of thing it does, with an example. The equation above each example is
the MathML fxTeX made of it, written into this page as it came out of the converter: nothing here
is a picture, and nothing is converted in your browser. Click any example to see its MathML.
The chemistry commands are mhchem's \ce and
\pu, and chemfig's, which fxTeX Pro draws as SVG with its chemfig module.
144 of the commands are in fxTeX Pro's optional packages - mhchem, chemfig and the
physics package - which a page has to ask for. To see how fxTeX compares with other converters, see
How we compare .

Physics package
The LaTeX physics package, beyond the commands above. This is an optional package: a page has to ask for it, with fxTeXPro.autoRender({ packages: ['physics'] }) or await fxTeXPro.usePackages(['physics']) before rendering, and until it does these commands are unknown. See fxTeX Pro .

Chemistry
Formulae, equations and quantities with mhchem's \ce and \pu, and structures with chemfig, which fxTeX Pro draws as SVG with its chemfig module. In fxTeX Pro both are optional packages, which a page has to ask for, as it does for physics : fxTeXPro.autoRender({ packages: ['mhchem', 'chemfig'] }). fxTeX has mhchem built in.
