This is due to composite units being built using the standard operator formatting and font sizes in SMath Studio.
I agree that an inline fraction operator would be nice, in particular for formulas embedded in text.
Yet, if you really want, you can define your own units. Note that you need to press Ctrl-K for entering special characters like / as parts of names.

Given the low resolution of the fonts at standard zoom level, the superscript font is hard to read, so this might be a matter of taste.
