Survey on the Use of Units in Scientific Domains
Through this survey, the CODATA Task Group on Digital Representation of Units of Measure (DRUM) aims to understand better the use of units in different domains. It is important to understand and represent the practices and needs of different domains.

Responses collected via this survey will be collected and transmitted to DRUM by Task Group member Steven Emmerson (UCAR/Unidata).

Does your discipline use either an official or a de facto standard representation of units? If so which? (For example, UCUM, QUDT, OM, SWEET, UNECE, MIXF, NCIT, …)
For your discipline, is there an equivalent international document to the IUPAC Green Book, the Astronomy IVOA ‘Units in the VO’ document, ISO 80000? (If so, please provide links.)
Are there any comparable national documents that are relevant? (e.g. the NIST SP811 guide to using the SI)
Please describe a challenging research question which is difficult to answer without clear and standardized units of measurement.
Please describe any issues of conversion, challenges in longitudinal data or other problems, that you may be aware of or have encountered.
Do you have an example in your discipline where a failure to properly represent or convert units of measure led to serious problems?
What domains do you interact with?  Are there research topics that require integration of data from different sources / fields where units become an issue?  If you aggregate data, how do you determine and then reconcile the units?
What resources do you commonly consult when needs or questions arise around units of measures? Which of these are accessible in digital formats? Which of these are accessible in machine actionable formats (e.g. database, JSON, XML, RDF, web service/API)?
Which  tools, packages, programming languages, or databases are predominantly used in your field or discipline? Which  file formats are commonly used in your fields / discipline?
What is the strangest unit you have come across?  (This can be amusing and instructive: Did you know that the speed of light is 1.803e+12 furlongs per fortnight and Harvard Bridge is 364.4 smoots long?)
