  The Reidemeister torsion construction can be applied to the chain complex
used to compute the Khovanov homology of a knot or a link. This defines a
volume form on Khovanov homology. The volume form transforms correctly under
Reidemeister moves to give an invariant volume on the Khovanov homology. In
this paper, its construction and invariance under these moves is demonstrated.
Also, some examples of the invariant are presented for particular choices for
the bases of homology groups to obtain a numerical invariant of knots and
links. In these examples, the algebraic torsion seen in the Khovanov chain
complex when homology is computed over $\mathbb{Z}$ is recovered.
