Beamer: sans-serif / serif question related to siunitx

beamersiunitx

I puzzled today for an hour to get the unit sans-serif.
I found that \usefonttheme[onlymath]{serif} helps but I am not sure if this is the correct way.
Question: Is it logical that I need \usefonttheme[onlymath]{serif} in order to have the units sans-serif?

% Based on https://tex.stackexchange.com/questions/66713/
\documentclass{beamer}

\usepackage{noto}
\usepackage{arevmath}
%\usefonttheme[onlymath]{serif} % <-- Un/Comment to see change

\usepackage{xfrac}
\usepackage{siunitx}
\sisetup{%
    per-mode = fraction,
    fraction-function = \sfrac,
    }

\begin{document}
 \begin{frame}
  Text appears in \textbf{sans-serif} font

  $x,2y,3z$ appears in \textbf{sans-serif} font

  $\SI{1}{\metre\per\second}$ units appears in \textbf{serif} font, would like it to be sans-serif
 \end{frame}
\end{document}

Edit: I now believe my question is a duplicate of sans serif font with siunitx.

As is discussed in sans serif font with siunitx, detect-all in sisetup will make the unit in sans serif font as is the text in the document.

Here is the test result.

[Tex/LaTex] sans serif math in tables and siunitx

With siunitx, there are a couple of potential approaches. First, as Stefan has said you can detect the current font:

\documentclass[paper=a4, fontsize=11pt]{scrartcl}
\usepackage{booktabs,lmodern,siunitx}
\usepackage{siunitx}

\newcolumntype{k}{%
>{$\mathsf\bgroup}l%
<{\egroup$}%
}


\begin{document}
\sffamily

\begin{center}
  \sisetup{table-format = 2.4,detect-family}
  \begin{tabular}{S
  k
  S[table-number-alignment = left]
  S[table-number-alignment = right]}
  \toprule
  {Some Values} & {Some Values} & {Some Values / \si{kg/m^2}} & {Some Values} \\
  \midrule
  2.3456 & 2.3456 & 2.3456 & 2.3456 \\
  {$\mathsf{a^2}$} & 34.2345 & 34.2345 & 34.2345 \\
  56.7835 & 56.7835 & 56.7835 & 56.7835 \\
  \bottomrule
  \end{tabular}
\end{center}

\end{document}

The second approach is to set the font used by siunitx for both text and math mode material to be sanserif

\documentclass[paper=a4, fontsize=11pt]{scrartcl}
\usepackage{booktabs,lmodern,siunitx}
\usepackage{siunitx}

\newcolumntype{k}{%
>{$\mathsf\bgroup}l%
<{\egroup$}%
}


\begin{document}
\sffamily

\begin{center}
  \sisetup{table-format = 2.4, math-rm=\mathsf, text-rm=\sffamily}
  \begin{tabular}{S
  k
  S[table-number-alignment = left]
  S[table-number-alignment = right]}
  \toprule
  {Some Values} & {Some Values} & {Some Values / \si{kg/m^2}} & {Some Values} \\
  \midrule
  2.3456 & 2.3456 & 2.3456 & 2.3456 \\
  {$\mathsf{a^2}$} & 34.2345 & 34.2345 & 34.2345 \\
  56.7835 & 56.7835 & 56.7835 & 56.7835 \\
  \bottomrule
  \end{tabular}
\end{center}

\end{document}

In both cases, I've used table-format = 2.4 as a shortcut to set up the reserved space. This is often easier than doing things piece by piece.

[Tex/LaTex] sans serif font with siunitx

From page 5 of the siunitx manual:

By default, all text is typeset in the current upright, serif math font. This can be changed by setting the appropriate options: \sisetup{detect-all} will use the current font for typesetting.

Thus, just replace the options detect-family and detect-weight in the preamble's \sisetup{...} instruction with detect-all, and your students will be all set.

Incidentally, if you run \addto\extrasngerman{\sisetup{locale=DE}} after loading the babel package with the option ngerman, you don't have to specify the options output-decimal-marker={\text{,}} exponent-product = \cdot, and number-unit-separator=\text{\,} explicitly while loading the siunitx package.

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc} 
\usepackage{lmodern} 

\usepackage[ngerman]{babel}
\addto\extrasngerman{\sisetup{locale=DE}}

\usepackage{siunitx}
\sisetup{detect-all} % note: just one option still needs to be specified

\begin{document}
\sffamily
\SI{1.23}{\%}

1,23\,\%
\end{document}
