The NASA QUDT Quantity Ontology

The QUDT Quantity Ontology defines physical quantity individuals and the expression of their magnitude in a chosen unit of measure.

The QUDT Quantity Ontology is a dataset ontology and uses the namespace http://data.nasa.gov/qudt/owl/quantity# and the prefix quantity for all internally defined resources.
