In this article, we focus on deriving an easily implementable and efficient
method of constructing units of the group ring of dihedral group. We provide
a necessary and sufficient condition that relates the units in the group ring
of dihedral group with the units in the group ring of cyclic group. Using this
relation and the methods available for inversion in the group ring of the cyclic
group, we introduce an algorithm to construct units efficiently and check its
performance experimentally.
