DBpedia defines datatypes for units and dimensions.

The page below shows a "hierarchy" of datatypes, although there's no such thing as subClassOf for datatypes (see #22). In PropertyMapping.unit you can specify: 

{{PropertyMapping | templateProperty = altura | ontologyProperty = height | unit = Length }}
  • Or a specific datatype, in which case the templateProperty carries a pure number, which is interpreted as the provided unit. Eg in Mapping_en:Infobox_street:
{{PropertyMapping | templateProperty = length_ft | ontologyProperty = length | unit = foot}}

In both cases:
