Unit of Measure Standard - v1.0
Context
Version 1.0 of the Energistics Unit of Measure Dictionary is intended to cover the needs of the oil & gas industry and as such is not an exhaustive list of all units of measure in existence. There are many units used in the medical, culinary, agricultural and other fields which are not relevant and so are not included.
The units in the standard are intended to be those used by the industry or which reasonably would be expected to be encountered.
The units are also oriented towards use in software. The Energistics Unit of Meaure work group generated the unit names, symbols, derived units and conversion factors with an eye towards implementability in software and databases, not so much for other uses like writing academic papers. There are other resources – like NIST 811:2008 – to aid in preparing manuscripts.
