Examples of units with non-integer exponents

[Chetlin]

Hi everyone,

Would anyone be able to give me a few examples of places where units with non-integer exponents come up? I know of a couple right now: noise voltage density (?) in electronics has units $\text{V}/\text{Hz}^\frac{1}{2}$ and the statcoulomb has equivalent units $\text{cm}^\frac{3}{2}\cdot\text{g}^\frac{1}{2}/\text{s}$.

Are there many other places? One answer here on Stack Overflow says that they are "quite common" but I can't think of any other places where they come up.

Thanks!

When writing the rate equations in chemical kinetics problems we often see non integer exponents for the concentrations. This leads to some interesting units for other factors in the equations.
