# How to put Angstrom

Can anyone tell how to put the capital Angstrom to express units. I have been looking for a package but I haven't found one yet.

The excellent siunitx package is there for you:

\documentclass{article}

\usepackage{siunitx}

\begin{document}

\si{\angstrom}

\SI{1}{\angstrom}

\end{document}
