Abstract

This document describes a recommended syntax for writing the string representation of unit labels (`VOUnits'). In addition, it describes a set of recognised and deprecated units, which is as far as possible consistent with other relevant standards (BIPM, ISO/IEC and the IAU). The intention is that units written to conform to this specification will likely also be parsable by other well-known parsers. To this end, we include machine-readable grammars for other units syntaxes.

Status of this document

This is an IVOA Proposed Recommendation made available for public review.
It is appropriate to reference this document only as a recommended standard that is under review and which may be changed before it is accepted as a full recommendation.
