Stere
The symbol for the stere, the unit of volume for firewood, shall be “st” and not “s”, which had been previously assigned to it by the CIPM. (page 50 of SI brochure)--JimWae 20:28, 2004 Dec 14 (UTC)


 * The change occurred in 1948 (ninth CGPM). Urhixidur 13:56, 2005 May 26 (UTC)

Ambiguity in defining volume function
In mathematics, there is presently some ambiguity in defining the volume function. I'm not qualified to write about this, but I am qualified to ask about it, so I'll ask anyone with a background in absolute geometry to lend a hand. (This ambiguity has significant impact on set theory.)

Volume function is pretty important in human physiology, especially in cardiology. Precise definition of volume within chambers during phases would be enlightening at the bedside of a heart failure patient.

What is the difference between m3/h and nm3/h?
We find air volume and liquid volume explained in m3/h and nm3/h. What is the difference between them?


 * Context would help in answering your question. The units of flow (not volume) cubic metre per hour (m³/h) and cubic nanometre per hour (nm³/h) differ by a whopping factor of 1027. If the second unit is actually cubic nautical miles per hour (NM³/h), the difference is a factor of 6&times;109 (6,352,182,208). Urhixidur 13:45, 2005 May 26 (UTC)

Nm3 is Normal meter cube : measured at 0 degree centigrade temperature and 1 atmosphere pressure. Since gas volume depends on both, you need to define the base for volume measurement, hence the N in nm3

I am a lay reader of mathematics and physiology. I believe air and liquid volumes are essential keys to understanding of cardiopulmonary physiology. Volumetrics is a term with great promise but not well established in medicine.

What symbol should Wikipedia use for the litre?
If you have an opinion, please express it at this RFC. Dondervogel 2 (talk) 07:44, 28 February 2021 (UTC)

Advanced mathematics in lead
It's intimidating that this article, which is mostly about an everyday physical concept, starts with links to Measure (mathematics) and Region (mathematics).

IMO the lead sentence should instead link "measure" to Measurement. Those other links can be saved for a late-in-the-article section titled something like "In advanced mathematics" or "Generalizations". Jruderman (talk) 22:47, 30 June 2024 (UTC)
