  The importance of dimensional analysis and dimensional homogeneity in
bibliometric studies is always overlooked. In this paper, we look at this issue
systematically and show that most h-type indices have the dimensions of [P],
where [P] is the basic dimensional unit in bibliometrics which is the unit
publication or paper. The newly introduced Euclidean index, based on the
Euclidean length of the citation vector has the dimensions [P3/2]. An empirical
example is used to illustrate the concepts.
