gml:DerivedUnit

Derived units are defined by combination of other units.  Derived units are used for quantities other than those corresponding to the base units, such as hertz (s-1) for frequency, Newton (kg.m/s2) for force.  Derived units based directly on base units are usually preferred for quantities other than the fundamental quantities within a system. If a derived unit is not the preferred unit, the gml:ConventionalUnit element should be used instead.
The gml:DerivedUnit extends gml:UnitDefinition with the property gml:derivationUnitTerms.
