...same way that the speed of light is defined by the definition of the meter... I suppose, it should be "meter is defined by the definition of speed of light"...? 195.113.228.67(talk) 17:15, 25 January 2011
Metrology in the balance fig 3 has a good schematic diagram of a Watt balance. Also discusses recent accuracies. Rod57 (talk) 01:20, 28 March 2011 (UTC)Reply
The article says the watt balance is better than the ampere balance because there's no need to measure distances. But the calibration of the watt balance requires measurement of speed ('v' in the article). And I would naively think measuring speed means measuring distance.
I'm sure there's an well known explanation but I would've liked to see it in the article. LegendLength (talk) 09:23, 5 October 2012 (UTC)Reply
U is traditionally used for potential ENERGY, not potential difference aka Voltage V. The use of the outdated term "Potential Difference" and the symbol U in this context creates a huge amount of confusion in introductory and even advanced physics. We should use Voltage and V in this article to avoid the same issue. — Preceding unsigned comment added by 71.183.128.65 (talk) 18:01, 28 November 2016 (UTC)Reply
The article mentions that『metrologists agreed to rename watt balances as Kibble balances』 but the name of the article is watt balance. Why don't we rename it if it's already been agreed to be renamed? Actually somewhat interested in the reasoning... Pax vobiscum, Emosy (talk) 03:41, 15 May 2017 (UTC)Reply
From 2016, not only the majority but all "...independent, reliable English-language sources..." will use "Kibble balance". Henceforth, any use of "watt balance" except for explanatory reasons can in fact be used as a divider between reliable and non-reliable sources, the review process will not let the old name through. And the proper case use is minor "w" for the spelled out SI-unit with symbol "W", capital "K" is for the inventor of the balance... 8-), cf. [1]. —Pietro MonterivaTALK 16:21, 10 June 2017 (UTC)Reply

It's been over a year now since the CCU made the renaming decision (in June 2016), and I see no evidence of any dissent or controversy about it. It seems all articles since then use "Kibble balance", and the relevant policy is WP:NAMECHANGES, which says "we give extra weight to sources written after the name change is announced". Therefore, I'm moving the page. Birdfern (talk) 03:17, 1 September 2017 (UTC). On second thought, I'm opening a move request rather than just moving it.

The result of the move request was: page moved. Andrewa (talk) 10:24, 9 September 2017 (UTC)Reply
Watt balance → Kibble balance – The Consultative Committee for Units (CCU) decided in June 2016 to rename the watt balance the "Kibble balance" in honor of its late inventor, Bryan Kibble. It's been over a year now since the CCU made the renaming decision, and I see no evidence of any dissent or controversy about it. In WP:NAMECHANGES, it says "we give extra weight to sources written after the name change is announced". The three post-June-2016 references in the article all agree that "Kibble balance" is the current name. Birdfern (talk) 03:42, 1 September 2017 (UTC)Reply

I think that the Article should state explicitly that the future numerical value of the Planck Constant was defined at CGPM 26; I do not see that it yet does so. 94.30.84.71 (talk) 09:54, 18 November 2018 (UTC)Reply
There is obviously something wrong in the description of the measuring procedure. The "v" component in the formula F = UI/v must be measured in the "moving" phase. During the "weighting" phase, the speed of the coil only has to be kept constant to ensure that the net force is zero. — Preceding unsigned comment added by 89.253.110.211 (talk) 07:41, 27 October 2019 (UTC)Reply
"Bryan Kibble and Ian Robinson invented the Kibble Mark II balance, which uses a circular coil and operates in vacuum conditions in 1990.[14] "
The sentence ought to be rearranged to avoid a paradoxical situation where the Kibble Mark II balance operates in the present and concurrently in 1990. 2600:100C:A121:CC1F:24C8:AAF0:80F2:F8E1 (talk) 00:59, 1 June 2024 (UTC)Reply
