How did it turn into 1/16th when the word ounce was derived from 1/12th? Novalia ( talk) 10:17, 5 June 2020 (UTC)
The tael should *not* be called the traditional ounce. The two units had different origins. Gamerktc12 ( talk) 11:38, 25 July 2012 (UTC)
What's "℥" ? In the UK, the symbol is "oz". -- Tarquin
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
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
"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)
The linked page has no information on how Pound-force is related to an Ounce-force.
Why is it "Oz" when there isn't a Z in 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)

Could add mention of these based on : in Simpson, A. D. C and Connor, R. D, 2004. The Mass of the English Troy Pound in the Eighteenth Century. Annals of Science 61 (3): 321-349, page 329: "From English usage and from Pegolotti’s account, we know that the ratio of the size of the English troy ounce (or the Bruges silver ounce) to the English tower ounce (or Cologne ounce) is 16:15, the ratio of Paris ounce to the Cologne ounce is 21:20, and the ratio of the eight-ounce Paris and Bruges gold mark to the six-ounce Bruges silver mark is 21:16.35 If these ratios are precise (and it is part of our purpose here to demonstrate that this is so) then, in terms of English troy grains, the Paris ounce is accurately 472.5 grains, and the tower or Cologne ounce is 450 grains, where the English troy ounce at 480 grains defines the troy grain."

Historically, people did not know or distinguish between weight and mass. Before Newton, we didn't have precise definition of force so I bet it would be meaningless to talk about the unit of weight in the past. While the concept of mass is not fully understood today, the definition of mass within the context of Special Relativity is well-defined. Special Relativity is a very appropriate model for most of the cases so long the curvature of spacetime is not significant. Weight is the measurement of the gravitational force that is exerted on a body within a gravitational field. I do not think people really wanted to measure the force albeit the need of scientific research. What people really wanted to know may be the mass which many people thought as the measurement of the amount of matter. Strictly speaking, mass IS NOT the measurement of the amount of matter. In fact, matter IS NOT a well-defined concept within Physics. Nevertheless, it is safe to say that the 'amount of matter' is at least 'directly proportional' to the mass although there isn't a time-independent proportionality constant. See also Force, Weight, Mass in special relativity, Mass in general relativity, Special relativity and General relativity and definition of matter Thljcl ( talk) 11:20, 5 April 2010 (UTC)
Perhaps we should have a box explaining the difference between mass and weight. Then in the article always call these units "units of weight" exclusively. Will ( Talk - contribs) 07:16, 5 December 2015 (UTC)
Calling the "ounce" (and pound") a "unit of mass" is wrong. We need some way to explain these units are "units of weight"—not mass. Now many users would be very confused. If we aren't careful, we could end up with an edit war.
My suggestion would be to have a box like a sidebar providing a brief summary of the difference between weight and mass. If the imperial system has a unit of measure for mass, we should provide links to it. Will ( Talk - contribs) 07:24, 5 December 2015 (UTC)
Well, such conversions assume 1G. Will ( Talk - contribs) 02:16, 16 December 2015 (UTC)
The problem is that there are really three separate units that are commonly referred to as an "ounce": ounce mass, ounce force, and fluid ounce (which is a measure of volume). We should either change the lead to say that the ounce is a unit of mass, weight, or volume, or we need to move this article to
Ounce (mass) and create
Ounce (force) to go along with
Fluid ounce. --

The article is missing information about the very close equivalence between the weight of a fluid ounce of water and an ounce of water and also between the weight of a pint of water and a pound of water.
16 fluid ounces = 16.6908 ounces i.e. about 4% more
so 1 pint = 1.043175 pounds i.e. about 4% more (needs to be said again)
