Siunitx: formatting range

Question

Following this, I obtain

\sisetup{
  range-phrase=—
}
\SIrange{40}{50}{\liter}

40 L—50 L

Is there a way that can give me output in this format?

40—50 L

Answer 1

Assuming you have access to a reasonably recent version of the siunitx package, I suggest you try

\qtyrange[range-units=single]{10}{50}{\liter}

Of course, the range-phrase=\textendash and range-units=single options may both be set as part of an \sisetup directive.

\documentclass{article}
\usepackage{siunitx}
\sisetup{range-phrase=\textendash, range-units=single}

\begin{document}
\qtyrange{10}{50}{\liter}
\end{document}
