[Tex/LaTex] conventional temperature symbol

stacking-symbolssymbols

Looking for a symbol for the thermodynamic concept of conventional Temperature corresponding to \SI{298.15}{\kelvin} or \SI{25}{\Celsius} it is basically an uppercase T with a lowercase c overlaying it. Couldn't see it in the Comprehensive LaTeX Symbol List or get it through DeTeXify.

The simplest approximation I have for it is by using the following:

\rlap{T}c

which gives the following symbol

Conventional Temperature

Or define a newcommand to give it \newcommand{\Tcon}{\rlap{T}c}

Ideally the c should be shifted up from the baseline but it is good for now.

So the question is: Is there already a symbol for conventional temperature?

Best Answer

One option, using \ooalign (a description of \ooalign can be found in egreg's answer to \subseteq + \circ as a single symbol ("open subset")). A sans serif and a serif variant are provided:

\documentclass{article}

\newcommand\convtemp{%
  {\ooalign{T\cr\hfil\raise.2ex\hbox{c}\hfil\cr}}}
\newcommand\Convtemp{%
  {\ooalign{\textsf{T}\cr\hfil\raise.2ex\hbox{\textsf{c}}\hfil\cr}}}

\begin{document}

\convtemp\quad\Convtemp

\end{document}
