When you edit a unit, double brackets appear around it.

$5\mathrm{Unit}\left(\frac{'\mathrm{kg}''m'}{'s'}\right)$

$5⟦\frac{\mathrm{kg}m}{s}⟧$

$\mathrm{combine}\left(\,'\mathrm{units}'\right)$

$\frac{1}{200}⟦\frac{mt}{s}⟧$

$\frac{\mathrm{Unit}\left('s'\right)}{}$

$\frac{1}{200}⟦\mathrm{sn}⟧$

$\frac{{\mathrm{Unit}\left('m'\right)}^2}{}$

$\frac{1}{200}⟦\mathrm{pz}⟧$
