#187 assigned enhancement


Reported by: Martin Vlietstra Owned by: Gunther Schadow
Priority: minor Milestone: Version 2.2
Component: unit definitions Keywords:


The Dalton (symbol Da) is not catalogued in the list. It is an alternative name for the atomic mass unit. In the 8th edition of the SI Brochure, it appeared to have equal status to the amu, but in the draft version of the 9th edition of the SI Brochure (Table 8) it appears to be preferred above the amu.

This seems to be a change of mind among SI committee. UCUM does not need to include multiple synonymous symbols, so we do not need to do anything about this. However, we could add some unit symbol for it specifically or at least cross reference it.

No decision yet. Open for discussion.
