  • @VladyslavSemenyuk Can you give some context where you want to use this symbol? For example if it is part of an url, I suggest the url or hyperref package. – aloneprism Sep 06 '18 at 12:31
  • Welcome to TeX.SE! The code is $\sim$. Or Alt+126 in ASCII character. – Sebastiano Sep 06 '18 at 12:32

If you are going to use it for e.g. values with units then it might be useful to use the siunitx package. You could then write:

\documentclass{article}
\usepackage{siunitx}
\begin{document}

\SI{\sim 10}{\meter}

\end{document}

Note: removed '\approx' from earlier version of this answer since it doesn't give the desired symbol.

    Awesome that you're making answers! Just a few pointers: What do you mean by using the \approx command? It gives a symbol like this: ≈, not this :~. Furthermore, try to be precise: that is the OP didn't mention units at all. Also: since it is already a suggested answer in the comments, you should at least acknowledge that too. - Again: it's great that you're trying to help, and that's only what I'm trying to do to! – Andreas Storvik Strauman Sep 06 '18 at 12:29

    No,\approx produces two superimposed tilde characters and not just one – AndréC Sep 06 '18 at 12:30
  • You're right about the '\approx' command. Not sure what you mean with the comments though. I didn't see anything like that, maybe it was added while I was typing my answer. Anyway, thank you for the pointers. – user169883 Sep 06 '18 at 12:32
