Dimensions of Planck’s constant =ML2T−1
Dimensions of moment of inertia =ML2
Ratio of dimensions of Planck’s constant and moment of inertia is ‌

[h]

[I]

ML2T−1

ML2

=T−1
Dimension of frequency =T−1
Dimension of velocity=LT−1
Dimension of angular momentum =ML2T−1
Dimension of time = T
Thus, ratio of dimensions of Planck’s constant and that of moment of inertia has the dimensions of frequency
