I can't quite figure that out. I suspect few will find it to illuminate anything. Which is a good reason to remove it. —Quondum04:02, 5 March 2019 (UTC)[reply]
I see what it's saying now: you can't put subscripts like "max" on the units, only on the symbol for the quantity. Usage tips like this don't belong in a navigation template. They belong even less when the usage tip is off-topic. This template covers base quantitites, not base units.--Srleffler (talk)03:13, 6 March 2019 (UTC)[reply]
This has way too much content for a navigation template. I'm inclined to prune it by about half. This template, per its name, should focus onbase quantities. What I have in mind is:
Keep the "Base quantity" table, but kill the "example" column.
OK, done. I kept the graphic but switched to the version without the arrows, since I suspect they will no longer be correct after the 2019 redefinition goes into effect.--Srleffler (talk)03:11, 6 March 2019 (UTC)[reply]
Correct or not, arrows don't belong in the graphic in the template at all: they are peripheral information. In the new SI, the arrows are somewhat arbitrary anyway; for example, the metre could have been defined in terms of the wavelength of the transition radiation of caesium. —Quondum04:19, 6 March 2019 (UTC)[reply]
