I would like to use LaTeX notation in physics texts. Thankfully, there is MathJax. MathJax renders LaTeX formulas in HTML documents for quite some time.

A simple mathematical formula:

\( a^2 + b^2 = c^2 \)

But physics require the rendering of a value with a unit. I use the siunitx package in LaTeX for this. These commands where not available in MathJax for a long time. There is a MathJax extension available since one year. This extension provides some of the functionality of the LaTeX package. Especially, the `\sisetup`

command is not working. The format of the output is not customizable as in LaTeX.

\begin{equation}
\Delta s = \SI{4.5e-2}{\meter}
\end{equation}
