quantitykind:AmountOfBiologicallyActiveSubstancePerMass
  a qudt:QuantityKind ;
  dcterms:description """"Amount of Biologically Active Substance per Mass" is the biological activity of a preparation, expressed in
    International Units (IU), divided by its mass, as in IU/mg. Pharmacology calls this the potency of a preparation.
    Since the IU is dimensioned as a mass equivalent (see quantitykind:AmountOfBiologicallyActiveSubstance), the
    quantity is dimensionless and is organized under Mass Fraction. It is not commensurable with a plain mass
    fraction, because the mass that one IU corresponds to depends on the substance and is resolved at the quantity
    level. Not to be confused with Specific Activity, the radioactivity of a material per unit mass."""@en ;
