message: I don't like trashing decent articles with an template, so for minor fiddles like this, the clean template above makes more sense.  
*I've been away south helping out with the post H. Katrina recovery, so I'm not up on a lot of the newer changes, like footnotes, or I'd do this myself. I've got about 3-4 more edit pages to pop off and finish in a string and being after midnight, I'm not going to research such now!
*The need I see is to move the legal cites down into the nice new footnotes.

message: It is infuriating the number of recipes that, due to the laziness of the writer or copier, fail to include the word "fluid" and yet it is implied with the item to be measured. Since when would you measure out 6 ounces of water? Or pizza sauce? Sometimes, it could be either weight or volume, but the frequent omission of the word "fluid" leaves it ambiguous.
This is one reason why I disdain the customary/imperial measures and prefer metric. At least there's no such thing as a "fluid gram" or a "mass/weight millilitre"!

text: Ah, no.  Granulated sugar is dry. ~ MD Otley (talk) 03:20, 4 November 2009 (UTC)
replies: text: I guess sugar is dry in the sense that it's dry to the touch, but it's still common to measure it in units of volume. For instance, when I cook rice, I measure it in cups, then add twice as much water. It even says to do so on the back of the package. Outside the US, deciliters (dl) are common for rice, sugar etc. So yes, I definitely see the problem; I don't think it's always clear whether to measure volume or mass, and 10 fl oz of sugar is very different from 10 oz of sugar. A sentence like "add 3 ounces of sugar and 6 ounces of water" would definitely confuse me. 75.80.168.147 (talk) 22:15, 29 November 2009 (UTC)

text: As the main said, no recipe would ever say to use a certain number of ounces of sugar:  sugar measurements are in teaspoons, tablespoons, or cups.  The same goes for other ingredients made up of many small pieces, like spices, flour, and loose grains.  Liquids use the same volume measures, but can also use fluid ounces, although that's not as common as fractions of a cup. ~ MD Otley (talk) 19:15, 13 September 2015 (UTC)

message: I am in my 30's. I was raised always using Floral Ounces. Now everyone uses Fluid Ounces. When did this change happen? Presidentbalut (talk) 20:28, 20 January 2014 (UTC)
thread_title:  When did Floral Ounce become Fluid Ounce? 

message: There is nothing how-to manual-ish about defining fluid ounces in terms of metric measure. It is how the articles on the international yard and pound, pint and gallon defines those units. The current definition is circular and fails to give the reader a quick reference point to the similarity and difference between the units by reference to a independent yard stick (so to speak). Moreover both US and Imperial fluid ounces are legally defined in terms of metric measure. — Blue-Haired Lawyer t 14:42, 20 August 2014 (UTC)
thread_title:  Definition 

message: Ounces are most commonly mass. The ounce-force exists but is rarely used.
When some one steps on a bathroom scale, they are measuring weight, in pounds and ounces. When a newborn baby is weighed it is weighed not "massed" and the weight is measured in pounds and ounces. When someone puts a letter on a postal scale it's weight is measured in ounces. These scales and all commonly used scales are incapable of measuring mass, they can only measure weight. Even a balance type scale cannot measure mass directly, it can only infer it from the relative weight of two objects.
I don't know what planet you're from, but on earth ounce is a measurement of weight, not mass!

replies: text: I'm from a planet where a pound is defined as  kilograms.  When I stand on a set of bathrooms scales, sure I'm measuring weight but the reading is in kilograms not newtons.  Of course, if I were on another planet, this wouldn't give me the correct mass, but the fact that these scales don't have the warning "for use on Earth only" doesn't seem to worry me very much.  Okay, it's true that scales can only measure weigh and that mass is then inferred and it's true that we speak of weighing things not massing them but that doesn't make the kilogram a unit of mass, which, by the argument presented here, it would be.  The kilogram is not a unit of force, nor therefore is the pound nor the ounce (as the pound is defined in terms of the kilogram and the ounce in terms of the pound).  They are all units of mass.

text: Please consult the legislation of the United States, the United Kingdom, Canada, and other countries where the pound and ounce are legally defined. They all say 1 lb = 0.45359237 kg. No gravitational fields or location is mentioned. This equation is valid everywhere. If a kilogram is a unit of mass, so is a pound, and so is an ounce. Some of the confusion has to do with the word weight which is ambiguous. Some textbooks and physics teachers insist that weight can mean only "force due to gravity," but nobody can control the English language. Like it or not, weight can and usually does mean "mass."

thread_title: Utter Nonsense!

message: 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)

thread_title:  conversion between ounces and fluid ounces of water missing 

message: The regulation cited (iirc 21 CFR section 101.9) is explicitly only about serving sizes in the context of nutrition facts, and also discourages using "fluid ounces" unless it is a beverage and more natural units like "one can" are not suitable. It alludes to package sizes having different rules. Package sizes use US customary fluid ounces, although I cannot find the law or regulation dictating this.
Reading the 21 CFR regulation cited in this article turns up something interesting: Because measures in fluid ounces should be rounded to the nearest 0.5 fl oz, and because servings are unlikely to be over 35 fl oz, the difference between 30 mL/oz and 29.58 mL/oz will never matter. Once you hit 35.0 fl oz (30 mL each), you have a problem because that is equal to 35.5 fl oz (US customary fl oz). But in practice, I doubt such a large serving would exist. Using numbers that large for teaspoons or tablespoons is forbidden, you have to switch to cups. As a result, ALL of these "household units" of volume will in practice be equal to the US customary units, because of the required precision (which is limited to a half-unit, except for the cup).
In other words, the fact that serving sizes use different units will never cause an observable difference in a label, due to the mandated lack of precision and the practical limits on a serving size. And the fact that the appropriate unit goes from teaspoon to tablespoon to ounce to cup as the volume increases, skipping ounce unless the item is a beverage. A sauce, or ice cream, are examples of foods that would skip from tablespoon to cup. 209.6.225.254 (talk) 00:35, 17 February 2024 (UTC)
