[Tex/LaTex] ± Symbol in text


I can't get a ± symbol to show up in my .pdf document, whether it be within a table, or in the main body of text. Can anyone offer any assistence ?

I have read everywhere it is \pm and would write as:

50\% \pm 2\%


50\% \pm{2\%}

As well as other variations.

Similar to Christian's answer, but siunitx will deal with the correct typesetting, be it text mode or math mode.


  separate-uncertainty = true,
  multi-part-units = repeat

Math mode: $\SI{50 \pm 2}{\percent}$

Text mode: \SI{50 \pm 2}{\percent}
