Those are probably fractional grains. https://en.wikipedia.org/wiki/Grain_(unit)

It was defined such that 252.458 units would balance 1 cubic inch (16 cm3) of distilled water at an ambient air-water pressure and temperature of 30 inches of mercury (100 kPa) and 62 °F (17 °C) respectively.

Nice and convenient.

That's the way I would have done it. Pretty intuitive.

So "7 1-2" should be read as 7.5? Do you know if there is a difference between "grs" and "GRS"?

[–] [email protected] 9 points 10 months ago (2 children)

Considering the active ingredients seem to be listed in bold, I think it’s safe to assume that it was just simpler to use all caps for one part of the label and lower case on the other half.

GRS probably stands for grains. A grain in 1/7000th of a pound, so these is actually not that much per serving. Unless this is using British Imperial Units, which are different from American standard Units. If it’s British imperial, I don’t know how much this is meant to mean.

Found some pics. Definitely 7 and 1/2.

Agreed. It sent me digging.

An avoirdupois pound is equal to 16 avoirdupois ounces and to exactly 7,000 grains. The conversion factor between the kilogram and the international pound was therefore chosen to be divisible by 7 with a terminating decimal representation, and an (international) grain is thus equal to exactly 64.79891 milligrams.

Pound(mass)

The Avoirdupois entry had a good visual representation as well as more weights history.

The "q. s." remains a mystery though.

The "q. s." remains a mystery though.

q.s. means quantum satis and is Latin for "as much as necessary". Which means they add enough for the right consistency or flavour or whatever, but the exact amount isn't given and might vary.

[–] [email protected] 2 points 10 months ago

Gotcha. Terrifying.

[–] [email protected] 3 points 10 months ago (1 children)

Big words big GRS, little words little grs. The GR and GRS is what should be questioned.

[–] [email protected] 1 points 10 months ago (1 children)

That makes sense. And the q. s.

[–] [email protected] 4 points 10 months ago (1 children)

q.s. - quantum sufficiat

as much as suffices; a sufficient quantity

Ahhh, ok. Thanks!

[–] [email protected] 1 points 10 months ago

Yeah. Lack of standard notation or standardized font for ingredients. No regulations in ppace for legibility.

[–] [email protected] 6 points 10 months ago

Oh, not grams. I thought the dosage seemed high.
