Hi All, I think the units database that we have as part of openEHR tooling allows for the addition of equivalent and language dependent expressions, as well as conversion where that is possible.
How about we make that available somewhere to get this going. It does mean we are not beholden to others and can know when we have UCUM compatible expressions (convert if necessary).
