    Angstroms in LaTeX

    Some time ago someone asked how to obtain the symbol for Angstrom units
    using LaTeX. Well its not elegant but:

    <br />
{\buildrel _{\circ} \over {\mathrm{A}}}<br />

    is generated by: {\buildrel _{\circ} \over {\mathrm{A}}}

    I suspect some of the braces are redundant.

    \buildrel _\circ \over {\mathrm{A}}
    Works too.

    Problem is this is math forum nobody uses angstroms.

    There is a simple command to produce a circle above a letter, but it doesn't look to good above a capital A. Click to see the code:

    \r{A}\r{o}

    This is another one, math-style, and seems to work well for A too:

    \mathring{A}\mathring{o}

    It is "proper" to unslant your A.

    The [tex][/tex] tags are only required on this site. In a LateX document it requires no such tags (and the \text{} should not be needed other that in math mode).

    Re: Angstroms in LaTeX

    Please ....

    Angstrom is a unit of length .... please do not use (never, NEVER EVER) italic units
    they have to be outside of math-enviroment or you make them non-italic (e.g.: $\mathrm{}$)

    Thus, \AA in text enviroment is the most suitable solution .... furthermore, do not forget the "\," between number and unit, else you cold have to fight on linebreaks and so on (e.g.: 123\,\AA).

    Regards

    I'm not poking fun at your comment, but you are aware that this thread is 5 years old?
