[443] - tentative update of Avogadro's number and definition value of AMU, needs some more checking of text and also needs more commentary to describe the update history and the new official status of the mol."
Table 3. in https://iopscience.iop.org/article/10.1088/1681-7575/aa950a/pdf
note from Clem: we should fix these. Believe it NLM may have changed it in their ucum converter
This I had already applied in a joint session with the Regenstrief people. [443]
I didn't see it in the ucum-essence.xml file. But now I understand that 'essence' is not the normative artefact. That was perhaps a misunderstanding on my part.
However, I think it also exposes a problem with UCUM - the normative definitions should be available in a machine-processable form, not just a table embedded in an HTML spec. At the least a machine-processable artefact should be automatically synced from the spec.
Decision from 17 February 2021 Board Meeting was to update all constants.
The Avogadro constant (definition of mole) was already updated to the 2018 value in
ucum-source.xml
and inucum.xml
. However,ucum-essence.xml
anducum.html
still have the older value and the latter is what is most visible on the website.
Need to adjust various mole-based values, e.g. picomole.
