Units Registry

The Units Registry provides a set of standard units that may appear in XBRL instances. As XBRL applications have emerged, unit declarations have appeared in XBRL instance documents having multiple names for equivalent meanings, and identical names having different meanings. The goal of the XBRL Units Registry (UTR) is to be a public, online data set that documents these units and their usage.

The Specification document listed below describes the UTR and the process by which it is is updated.  This process is intended to maximise the utility and longevity of the new units and the taxonomies that use them. 

The latest version of the UTR will always be on the URL www.xbrl.org/utr/utr.xml.
