International System of Units was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated.

As a matter of background for the Introduction section, I think providing the French translation ( French: Systéme international d'unités) can help explain how the abbreviation "SI" arose, so I added it to the article. My edit was reverted by someone saying "Not required in English Wiki ( MOS:FOREIGN)". Because of the abbreviation and the prevalence of this term in international use, I suggest there is more justification for including this term than would ordinarily be the case for a foreign-language translation. I see that Britannica puts the French in boldface in its opening sentence. There is also a very close relationship between France and the SI system, e.g. as explained here. — BarrelProof ( talk) 18:15, 16 December 2022 (UTC)
The origin of the name SI is hidden away very far down in the article. Mateen Ulhaq ( talk) 04:23, 16 June 2023 (UTC)
There used to be an Introduction section which competed with the rest of the article. First, the lead is supposed to be the intro ( MOS:INTRO). Second, two sections titled in the same way (e.g., #History) cannot receive different incoming links. Third, many Intro subsections were very long, some were even longer (in prose) than the corresponding section outside of the Intro section, which contained mostly lists (via templates). If the intent was to create an introductory article, then it should have been split into Introduction to the International System of Units instead. It felt as if someone didn't like the existing article and decided to write a new one, except it was left in a subsection. fgnievinski ( talk) 04:46, 14 August 2023 (UTC)
This article is too long and should not duplicate content in subtopics, such as SI base units, SI derived units, SI prefix, etc. Other notable subtopics could be mover into the respective main articles, e.g., SI#Realisation. fgnievinski ( talk) 05:13, 14 August 2023 (UTC)
There is some disagreement about the meaning of "gram per cubic centimetre" and "kilogram per cubic metre". Editors are invited to comment at the g/cm^3 talk page. Dondervogel 2 ( talk) 13:56, 27 October 2023 (UTC)

This 2013 listing was tagged with {{ GAR request}} in July. There is significant amounts of uncited material, and a behemothic notes section which seems mostly irrelevant, tbh. ~~ AirshipJungleman29 ( talk) 22:28, 20 November 2023 (UTC)
This article was recently tagged "More citations needed", but it has 97 references and not a single "citation needed". Can you help me understand the reasoning? @ AirshipJungleman29 @ CactiStaccingCrane Johnjbarton ( talk) 02:56, 14 January 2024 (UTC)
This article is one of the top 20 most viewed Physics articles that are assessed a C rating.
After removing material we don't think contributes to Wikipedia goal for this article, then we need to add citations to the rest. Johnjbarton ( talk) 03:56, 14 January 2024 (UTC)
As this article is about the SI system, I don't think any other units are notable here without an important and specific connection to the SI.
In a recent edit @ Dondervogel 2 added the decibel. I don't see how it is special and think it should be removed. Johnjbarton ( talk) 17:11, 16 January 2024 (UTC)
Table 8 also includes the units of logarithmic ratio quantities, the neper, bel and decibel. They are used to convey information on the nature of the logarithmic ratio quantity concerned. The neper, Np, is used to express the values of quantities whose numerical values are based on the use of the neperian (or natural) logarithm, ln = loge. The bel and the decibel, B and dB, where 1 dB = (1/10) B, are used to express the values of logarithmic ratio quantities whose numerical values are based on the decadic logarithm, lg = log10. The statement LX = m dB = (m/10) B (where m is a number) is interpreted to mean that m = 10 lg(X/X0). The units neper, bel and decibel have been accepted by the CIPM for use with the International System, but are not SI units.
We have a long section called "Lexicographic conventions" much of which reads like a guide contrary to WP:NOTGUIDE.
I propose to reduce the General rules subsection to a sentence and a for-example discussion of the figure. I think that gives the general idea without the detail. Any real use of the detail would need to consult the brochure anywayl. Johnjbarton ( talk) 19:32, 16 January 2024 (UTC)
The section "Realisation of units" has a lot of duplicate material.

I think the weakest part of the article now is discussion of the defining constants and how they relate to the base units. This is the heart of the (new) SI. Johnjbarton ( talk) 01:56, 18 January 2024 (UTC)
A bit down in the text on the page is the following equation:
1 kg = (299792458)2/(6.62607015×10−34)(9192631770)h ΔνCs/c2. Not sure if the paste worked as intended but you can find the original equation on the page. The problem is obvious, the units on the fraction is 1/kg rather than kg and it is inverse of the equation that follows The speed of light squared is in the nominator rather than the denominator etc. It appears that nominator and denominator has switched places in the numeric fraction and also there ought to be an equal sign (=) between that fraction and the formula that follows it. Right now they are all placed together making the resulting value 1 without any units.
Please fix. AlfSalte ( talk) 04:45, 28 April 2024 (UTC)
