Math & Science ⇒ siunitx | Atoms as Units

[niles]

Hi

I wish to write the units of a quantity as atoms/s, in other words something as

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage[per-mode=symbol, exponent-product = \cdot]{siunitx}

\begin{document}
\[
\SI{1e12}{\atoms\per\second}
\]
\end{document}

Is there any way to achieve this with SIunitx? Thanks for any help.

Best,
Niles.

Simply declare a new unit as described in Section 4.5 of the siunitx manual.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{siunitx}

\sisetup{
  per-mode=symbol,
  exponent-product = \cdot
}

\DeclareSIUnit{\atom}{at}

\begin{document}
  \[
    \SI{1e12}{\atom\per\second}
  \]
\end{document}
