# ! Missing $inserted error Density & 7.7 g/cm^3 \\ \hline  I am using this for a table and its showing me an error "! missing$ inserted" , even though my purpose of using '^' is getting fulfilled.

• Welcome to TeX.SX! You need to be in math mode ($) every time you use ^. – TeXnician Jun 27 '17 at 12:52 • Or if you don't want to bother with math mode, consider using siunitx – user36296 Jun 27 '17 at 13:02 • Thanks @texnician , how can i modify this, i mean what part of the text should be between$...$? – Dhruv Gulhar Jun 27 '17 at 13:03 • For example \documentclass{article} \usepackage{siunitx} \begin{document} \SI[per-mode=symbol]{7.7}{\gram\per\cubic\centi\meter} \end{document}  or \SI{7.7}{g/cm^3} – user36296 Jun 27 '17 at 13:05 • The other option would be a g/cm$^3\$ or if you do not want that g/cm\textsuperscript{3}. – TeXnician Jun 27 '17 at 13:13

As pointed out by the TeXnician in his/her/its comment ^ only works in math mode.

To circumvent getting in this situation in the first place, I would rather use siunitx instead of manually writting the unit.

\documentclass{article}
\usepackage{siunitx}

\begin{document}

\SI[per-mode=symbol]{7.7}{\gram\per\cubic\centi\meter}

\SI{7.7}{g/cm^3}

\end{document}
