I use the gensymb package so I could use \celsius, but I get two warnings.

Code: Select all

Package gensymb Warning: Not defining \perthousand.
Package gensymb Warning: Not defining \micro.

What is going on?

Please build a proper minimal working example (MWE) that reproduces the problem. With some code it is easier to see what is not working.


Best regards and welcome to the board

Sorry, unaware of MWE!

Code: Select all

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

\begin{document}
  Blah blah blah \celsius
\end{document}

The warnings are as in my previous post.

Hm. Seems that the package simply refuses to define these two macros and doesn't give any further information about that. But Section 3 of the package manual suggests as "optimum case" to load the textcomp package before gensymb.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{textcomp,gensymb}

\begin{document}
  Room temperature is 21\celsius.
\end{document}

If you want to use these symbols in the context of physical units, you may take a look at the siunitx package instead.

Awesome! Thanks.
