Relationship to the international prototype kilogram
[edit]If I understand this business correctly, if one changes the definition of the kilogram such that V_90 = V_SI, then a new kilogram will be defined based off of these exactly-defined values for the Josephson constant and the Von Klitzing constant and the international prototype kilogram will no longer be necessary. If this is true, I think this is an important point that should be mentioned in this article.

- I agree that something about this should be mentioned. Although it is quite possible that the international prototype kilogram will no longer be necessary in 10 years, I have the impression that the SI folks were not intending to set V_90 = V_SI ... I thought they would use a slightly different numerical value, one that would improve the agreement between the new kilogram and the old kilogram. I could be wrong, I'm not an expert on this and just guessing from vague recollection. --Steve (talk) 16:18, 8 December 2012 (UTC)
Introductory paragraph
[edit]This article may benefit from an introduction to explain the principle behind different unit systems to non-experts who may not understand most of the rest of the article.----Ehrenkater (talk) 15:09, 18 February 2019 (UTC)
Rescaled natural units: OR?
[edit]The section Conventional electrical unit § Comparison with natural units is a bit of a stretch, and I suspect is completely original research. The definition of the second is necessary to determine the magnitude of many of the conventional electrical units. While these units go a long way in using natural constants, the omission of a necessary defining constant (the caesium hyperfine transition frequency) from the equalities at the start disqualifies this as a form of scaled natural units. This would have been considerably more obvious if the units themselves were listed in the table. Since the SI has now completely caught up with this status, the point that it is a "scaled nearly natural" system of units has no real value any more. I propose deleting this section. —Quondum 20:53, 4 July 2019 (UTC)
