Is there such thing as irrational units of measurement?

Such as meters/sqrt(s) or kg/sqrt(m). Is there any use for this?

There is something called spectral density which is measured in  Volts/sqrt(Hz) or something similar, the voltage measured at each frequency. This starts to make sense when you consider that power is proportional to the square of voltage, the power spectral density is in Watts/Hz.
