- RFV for the sense “A metric approximation of the ounce, usually taken as 20 or 30 millilitres (for volume) or grams (for mass).”
- In the Netherlands, it's 100 grams. —CodeCat 22:56, 3 February 2014 (UTC)
- w:Ounce#Metric ounces says that it's 25... But either way, this is not an RFV thing because the essential part of the definition ("A metric approximation of the ounce") is obviously going to pass. --WikiTiki89 22:59, 3 February 2014 (UTC)
- A link to the Wikipedia chapter mentioned above would clarify this entry remarkably. --Hekaheka (talk) 05:37, 4 February 2014 (UTC)
- It's not hard to find citations that define a metric ounce as 30 grams; in fact, I found more of them than citations that define it as 28 grams. I also found citations defining it as 25 grams or "28.35 g […] not 28 g". See Citations:metric ounce. - -sche (discuss) 17:33, 4 February 2014 (UTC)
- 28.35 is not called metric ounce. Rather, it is the (approximate) conversion of the (avoirdupois) ounce into metric. The citation metioning it does not say metric ounce, but rather metric ounce weight. That is, the weight of the ounce in metric. The 25g ounce (which I believe is what is normally meant in the English speaking world by metric ounce) is used in connection with the metric pound (or French livre = 500g) because an exact number of them are needed to the pound. The 28g and 30g ounce, on the other hand are used where the original specification was in Imperial units, or some other customary units and there is a need to have something like the same amount again but measured on metric scales.

- At present, the only senses which are supported by citations are "25 grams" and "30 grams". metric inch is also citable. - -sche (discuss) 22:37, 15 March 2014 (UTC)
