Merge proposal
editThe article List of examples of lengths doesn't seem any more necessary than the hypothetical article List of commanders-in-chief of the United States Armed Forces. – MrPersonHumanGuy (talk) 10:59, 30 May 2024 (UTC)
- My translation of the case is that this is a merge for overlap; that seems fair enough. Support the proposal to merge, but even a redirect would be fine. Klbrain (talk) 09:16, 16 October 2024 (UTC)
- Merger complete. Klbrain (talk) 12:11, 16 November 2024 (UTC)
Quetta
editSince Quetta (=1030) is now an official SI prefix, should a section for quettametre Qm be added? There isn't much information to put in it though... 2A0A:EF40:E4F:1:47B5:F2BA:D603:1C82 (talk) 20:53, 12 December 2024 (UTC)
