Another unit that is expressed in fractional powers is the esu
(electrostatic unit); it is in fact defined as

esu := cm^(3/2) g^(1/2) s^(-1)

See here for a nice explanation :

Now, as has been noted before, it's almost always possible to rewrite
your equations to eliminate fractional powers, but from the end-user
standpoint, reformulating an equation is more difficult and
potentially error-prone than simply implementing an existing one...
