Units in LaTeX without making an italic font

Question

I wish to write a unit in LaTeX which should not be typeset in italics. My current code is Log Ejected Density $(\frac{g}{cm^{3}})$, which sets the unit italicized. Is there any package I can use to get a roman shape for the unit? I am using ShareLaTeX.

From here: http://www.ctan.org/pkg/siunitx But if you use just few times, you can use \mathrm{cm}^3. — Sigur, Aug 28 '16 at 18:33
@Sigur Remember the spacing between number and unit \mathrm{\,cm}^3 — Holene, Aug 28 '16 at 18:36
if you use just few times: \documentclass{article} \usepackage{textcomp} \let\sup\textsuperscript \begin{document} Log Ejected Density (g/cm\sup3) \end{document} — Fran, Aug 29 '16 at 06:20

Load the siunitx package. You can then enter units via the \si macro and a fairly natural looking input syntax.

The following screenshot shows three possibilities for the combination of units you mentioned in your posting. Choose whichever display method best suits your preferences. (Speaking for myself, I would not use the fraction method if the document is single-spaced.)

\documentclass{article}
\usepackage{siunitx}
\begin{document}
Log Ejected Density (\si{\gram\per\centi\meter\cubed})

Log Ejected Density (\si[per-mode=symbol]{\gram\per\centi\meter\cubed})

Log Ejected Density $\bigl(\si[per-mode=fraction]{\gram\per\centi\meter\cubed}\bigr)$
\end{document}

You should look into the siunitx package.

\documentclass{article}

\usepackage{siunitx}

\begin{document}

Numbers and units: $m = \SI{5.98}{\micro\gram}$

Numbers: $N_A = \num{6.022e23}$

Units: \si{\milli\pascal}

\end{document}
