The _IfcMeasureResource_ schema specifies units and defined measure types that may be assigned to quantities.

> NOTE  The fundamental unit types used in this schema are based on the SI system defined in ISO 1000+A1, 1992, 1998. Units in measurement systems other than SI may be derived using this schema. Many definitions declared in the _IfcMeasureResource_ schema is adapted from [ISO 10303-41](../../bibliography.htm#iso-10303-41){ .int-ref}
