Talk:Ounce

From Wikipedia, the free encyclopedia

This article, as well as that for pound (mass), need extensive review and checking for correctness.

[edit] Symbol

What's "℥" ? In the UK, the symbol is "oz". -- Tarquin

That symbol is ancient and was especially common in apothecary usage. Christoph Päper 07:34, 22 May 2006 (UTC)

[edit] Grams in 1 oz.

One ounce of gold is always 31.1 g.

Really? Isn't it, as the article says, 31.104... g? 03:38, 13 May 2006 218.102.71.117

Does one always have to insert “approximately” or “circa” even when it’s obvious? Christoph Päper 07:34, 22 May 2006 (UTC)

There are 454 grams in a pound, and 16 ounces in a pound, so divide 454 by 16 and you get 28.375 grams in 1 oz. Will someone please replace 28.35 with 28.375? 21:19, 21 May 2006 24.0.71.248

An avoirdupois pound is exactly 453.59237 g today, which makes an avoirdupois ounce about 28.35 g indeed. Christoph Päper 07:29, 22 May 2006 (UTC)

[edit] How much the hell is an ounce?

"A troy ounce (abbreviation: t oz) is equal to 480 grains. There are 12 troy ounces in a troy pound. Consequently, the international troy ounce is equal to about 31.103 476 grams." Excerpted from the article. An ounce, conversion systems available online say, is 28.3495 grams. If the information is wrong it is grossly misleading. —Preceding unsigned comment added by 59.91.253.63 (talk • contribs)

You didn’t read the article, did you? Christoph Päper 19:22, 27 August 2006 (UTC)

[edit] Ounce (unit of force) see Pound-force

The linked page has no information on how Pound-force is related to an Ounce-force.

That is entirely the fault, and the responsibility, of User:Fibula. There was nothing there when he removed it from here, and there still is nothing there. As far as I can see, there wasn't any real good reason for him to remove it from here, either. Gene Nygaard 21:56, 6 October 2006 (UTC)
It is a while ago now, but I believe my reasoning was as follows. In the case of the term "pound", the structure of the Wikipedia articles distinguishes between the units of mass (Pound (mass)) and the units of force (Pound-force), with the general distinction between units of mass and force being explained in the article on Weight. I was attempting to conform the structure of the article(s) on the term "ounce" to that of those on the related term "pound". I do not know enough about the existence and use of the term "ounce" as a unit of force, so I did not want to create a new article, say, Ounce (unit of force). Instead, I pointed the user towards the existing article Pound-force. I'll add a sentence to the latter article to deal with the relationship. Fibula 23:21, 20 December 2006 (UTC)

[edit] Origin of "Oz"

Why is it "Oz" when there isn't a Z in ounce?

I was wondering the same thing.

[edit] Marie Thersa ounce

does this actualy exist? google searches go round in circles. the name doesn't make any sense - *why* should Ethiopia have a 'marie theresa' anything? think this subsection should be deleted unless someone can verify it. raining_girl 19:26, 14 November 2006 (UTC)

Maria Theresa thaler -- but I do not know whether it was used as a unit of weight besides currency. Christoph Päper 18:15, 16 November 2006 (UTC)
if anything that makes me doubt the existence of the ounce more, as it isn't mentioned anywhere. Does however explain why there would be a Maria Theresa anything in Ethiopia.. Still think this is worth considering for deletion. raining_girl 14:35, 17 November 2006 (UTC)

IT WAS USED AS CURRENCY, AND IS STILL BEING MINTED....BUT IT IS NOT A FULL TR OZ. OF SILVER. —The preceding unsigned comment was added by 205.208.227.29 (talk • contribs).

It seems from the Maria Theresa thaler article that a huge number of these coins ended up in Ethiopia, but not only was it not a troy ounce of silver, it was not a troy ounce in total, instead being 28.0668g and so closer to an avoirdupois ounce. --Henrygb 16:16, 1 March 2007 (UTC)
