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 : http://www.tf.uni-kiel.de/matwis/

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...
