Math & Science ⇒ siunitx | Unit as a Fraction

[ghostanime2001]

I am using siunitx package and I want to have J/atom as a fraction. How can I do that?

Code: Select all

\SI[per-mode=fraction]{2}{\metre\per\second}

You can set this globally, by adding \sisetup{per-mode=fraction} to the preamble. You can also specify which function to use, \frac, \dfrac, \tfrac or \sfrac (the latter requires the xfrac package), with fraction-function=\dfrac.
