- $\mathring {\mathrm A}$
The angstrom is a metric unit of length.

The symbol for the angstrom is $\mathring {\mathrm A}$.
The $\LaTeX$ code for \(\mathring {\mathrm A}\) is \mathring {\mathrm A} .
Linguistic Note
The word angstrom is derived from a Swedish name, and properly has diacritics: ångström.
However, this "correct" presentation is tedious to implement and a nuisance to maintain, so $\mathsf{Pr} \infty \mathsf{fWiki}$ prefers the simple version angstrom.
Its symbol, however, does need the small circle above the A in order to be accurate and unambiguous.
This, unfortunately, is not straightforward to render in $\LaTeX$ without including further expansion sets.
Hence the $\LaTeX$ form as $\mathring {\mathrm A}$ (not a strictly accurate rendition) is how it is presented on $\mathsf{Pr} \infty \mathsf{fWiki}$.
