replies: text:  That's because all occurrences of "metre" were removed on 28 July. I found the inconsistency abhorrent, but the article seems fine (to me) after those edits. Perhaps someone should look at the convert template though. I had to replace it with manual unit conversions to achieve consistent spelling. Dondervogel 2 (talk) 20:38, 19 August 2020 (UTC)
thread_title:  "Metre" or "meter"? 

message: This article isn't very accessible, since most of the measurements are cited in mm. I would edit to include inch measurements as well as metric myself, but all edits to wikipedia are reverted. This is an article about a standard unit in the imperial system. If anything should refer to imperial units, an article about imperial units should refer to imperial units.  — Preceding unsigned comment added by 2600:6C4E:1200:BD:2D4E:4551:5399:8014 (talk) 22:24, 10 September 2020 (UTC)
replies: text: The purpose of converting to millimetres is to distinguish between multiple different definitions of "foot". Converting to inches would not achieve that because the inch is at least as ambiguous as the foot, so the reader would learn nothing useful. It probably is worth mentioning (if not done already) that some "feet" were divided into 10 inches and some into 12. Dondervogel 2 (talk) 07:01, 11 September 2020 (UTC)

message: dear all,
the Wiki page for the old measure of the 'palm' [see Palmo (unità di misura) - Wikipedia] offers a link to a pdf-source named "Antiche pesi e mesure" [i.e. Ancient weights and measures] (retrieved via Wayback Machine (archive.org)) which, translated from Italian, says the following on the unit 'foot' (piede):
"A linear unit of measurement that differs from place to place. 
The Neapolitan 'foot' (piede napolitano), used since the 11th century, was equivalent to 0.3349 metres. 
In the Kingdom of the Two Sicilies, the French foot (piede francese) or royal foot of Paris (piede regio di Parigi) was also used, which was equivalent to 0.324839 metres (today estimated to be 0.324864 metres)."
Interesting is that the article cites the following old 19th C. sources, all in Italian:
1° :  Antonio Pasquale Favaro: "Metrologia o sia Trattato Generale delle Misure, de' Pesi e delle Monete." [Metrology or General Treatise on Measures, Weights and Coins]. Napoli: Gabinetto Bibliografico e Tipografico, 1826; 
> Tavole delle Mesure Antiche [Tables of Ancient Measurements], p. 88 : 
piede di Parigi = 0,3248 m 
2° :  Carlo Afan de Rivera: "Tavole di riduzione de' Pesi e delle misure della Sicilia Citeriore in quelli statuiti dalla legge de' 6 aprile del 1840". [Tables of Reductions of Weights and Measures of Sicilia Citeriore in those established by the Law of 6 April 1840]. Napoli: Stamperia e Cartiere del Fibreno, 1840; 
3° :  Angelo Martini: "Manuale di metrologia ossia Misure, Pesi e Monete in uso attualmente e anticamente presso tutti i popoli antichi". [Handbook of Metrology i.e. Measures, Weights and Coins in Current and Ancient Use by All Ancient Peoples]. Roma: Editrice E.C.A., 1976, a facsimile reprint of the original Turin edition of 1883.
(> It is clear that there's a 'before' and 'after' 1840 situation regarding these old units of measurements, due to a Law dating from April 6, 1840)
Maybe, this pdf-source can be checked by an editor fluent in Italian to ascertain if the measurement equivalents in metres are correctly cited from one of the 3 old bibliographical sources above.
If yes, then this info can be added to the article in some way...
PS : regarding the denomination "Sicilia Citeriore"
'citerióre adj. [from Latin citerior -oris, compar. of prep. Citra "on this side"]. - Which is located on this side, towards us (with respect to another part of the region, which is said to be ulteriore'); it is usually used in geographical determinations of the ancient world (Spagna c., Gallia c.), and in administrative designations now disused, such as Calabria c., Abruzzo citeriore. (translated from citerióre in Vocabolario - Treccani).
It therefore must be making reference to the Kingdom of the Two Sicilies (1816-1860), of which Naples was the capital.
Sicilia citeriore must then refer to all of the Italian Peninsula south of the Papal States, which covered most of the area of today's Mezzogiorno, as compared to the island of Sicily itself which would then be considered Sicilia ulteriore.

thread_title:  "Evaluation of additional 19th C. Italian sources on the foot as used in Italy" listed at [[Wikipedia:Redirects for discussion|Redirects for discussion]]

message: The Harappan equivalent is stated in the article as "[...] a foot of  333.5 mm (13.2 in) [...]". In the cited source, on page 117, it is stated as "[...] the foot (13.2 inches or 33.35 cm) [...]" with the metric in centimeters instead of millimeters. However, if you convert either metric value into inches, you get 13.129921 inches which does not round to 13.2in. What appears to have happened is a typo in the cited source where the author transposed the two decimal digits of the metric value (from 33.53 to 33.35) since 33.53cm does convert to 13.2in. If so, then the value listed here should be 335.3mm (if we stick with millimeters instead of the centimeters of the source).However, I am not sure what to actually do for this article since, on one hand, there is an obvious typo in the cited source which creates an easy to see mathematical error in this article but, on the other hand, we are also supposed to stick with what is stated in the source. — al-Shimoni (talk) 12:34, 10 November 2023 (UTC)
replies: text: IMO, you should take the 13.2 inches as the original data and correct the author's math error.  That is a sensible and reasonable thing to do. But beware of excess precision in your conversion. So just use , which returns "" (so correct to nearest 1 mm, which is appropriate given that the original measurement was (presumably!) correct to nearest  of an inch).

thread_title:  Harappan foot measure error in source 

message: A recent series of edits by  made the first paragraph of the US survey foot section read
:In the United States, the meter was defined by the Metric Act of 1866, and ratified by the Mendenhall Order of 1893, as exactly 39.37 inches, making the US survey foot  meter or approximately 0.304 800 609 601 219 m.A. V. Astin & H. Arnold Karo (1959). "Refinement of values for the yard and the pound". . Washington DC: National Bureau of Standards. Republished on National Geodetic Survey web site and the Federal Register (Doc. 59-5442, filed June 30, 1959)
I reverted this portion of the edit. For one thing, the Metric Act of 1866 does not say it is defining the unit (or any other metric measure) it says it is listing equivalent values. It does not say which is a mathematical conversion of the other. Also, the approximate length of the foot given in meters is given to an extraordinary precision. I suspect this much precision is not justified, and would want to see a reliable source that explains how this is justified.
In addition, the Metric Act of 1866 did not make the US survey foot equivalent to a particular fraction of the meter, it made the foot, as enforced in the United States, equivalent to a particular fraction of the meter. The US didn't have two different feet until the invention of gauge blocks (in practice) or until 1960 in terms of the government's position.
Finally, the passage makes it seem as if the 1893 Mendenhall Order ratified the idea of defining the meter in terms of the foot. The reverse is true. The Office of Standards of the Coast and Geodetic Survey found the standard yard and standard pound unstable, and increasingly favored the standard meter and kilogram which they possessed. Mendenhall finally made it official with his order: US customary units were actually based on metric standards. Jc3s5h (talk) 02:01, 19 April 2024 (UTC)
