Using

This extension creates a shortcode si for setting SI values and units. The structure of the shortcode is as follows

{{< si 1.45 m s-1 >}}

Briefly, this extensions reformats the space separated items inside the shortcode into a series of formatted entries. All spaces are converted to non-breaking spaces. Trailing numbers are formatted as exponents. Some other helpful functions are conversion of +- into ±, some shortcuts for harder to type units such as Å and Ω and rewritting of E exponents into ⨉10.

Because the output is purely unicode, subscripts and superscripts, this extension is fairly agnostic in terms of output formats: HTML, Typst and LaTeX have been tested and work. There is no obvious reason why other formats would not work.
