Fluid ounces refers to volume like milliliters whereas regular ounces refer to weight like grams. Ounces by weight and ounces by volume are ONLY comparable when you are measuring water or other liquids with a similar density. Flour, on the other hand, is a totally different ballgame and a confusing one to boot. See how confusing it is? I mean, who do we need to petition to have fluid ounces changed to be called something totally different flounces? On the left is 8 ounces of flour by weight, and on the right is 8 ounces of flour by volume aka 1 cup.
Weigh out 8 ounces of flour and 8 ounces of water on a scale and this is what you get. Visually it looks like you have a lot more flour than water, but they weigh the exact same amount. On the left is 8 ounces of flour by volume and on the right is 8 ounces of water by volume.
Basically, what you see here is 1 cup of flour and 1 cup of water. My advice? It just confuses things. One of the beautiful things about the metric system is that there is no confusion. Grams are weight, milliliters are volume. If you see grams, grab your scale. If you see milliliters, grab your liquid measuring cup. However, once you start measuring dry ingredients, which often have varying densities, the two numbers will not match.
The volume is the same, but the weight is different remember: lead and feathers. Grams on the other hand, being a much smaller unit of measurement, make it easier to be incredibly precise. No wonder the cake is too dry…. Here you can see what I mean. The cup on the left was measured using the fluff, spoon and sweep method, while the one on the right was scooped right out of the bag. With a scale!
In grams! First, fluff up your flour by stirring it in the bag or, better yet, pour it out of the bag into a large canister which will do a great job of aerating on its own. Then, spoon flour and sprinkle it into your measuring cup. Rather, get a big spoonful of flour and sprinkle it into the measuring cup. Try this out a few times with a scale handy, and see what weight you get for 1 cup of flour.
You should see about grams of flour per level cup. Now just for comparison, go scoop a big cup of flour right out of a bag. Really dig your cup in there. Level off the top, then weigh the flour. Notice a difference? I bet you will! Those extra 30 or more grams of flour can really make a difference when baking, as extra flour can lead to dry or dense cakes and cookies. Cocoa powder is another ingredient that can be compacted, so using either weight or the fluff, scoop and sweep method is useful here as well.
Dry and liquid ounces are slightly different measurements. While dry ounces are a measurement of weight, liquid ounces are a measurement of volume. For solids, choose a dry measuring cup that uses ounces or something that can be easily converted to ounces. Put the ingredient being measured in a wide-mouthed container. You will be better able to put the measuring cup into the container if it has a large, open mouth. If the ingredient is not currently in an open-mouthed jar or bag, pour it into a bowl before you measure it.
Dip a measuring cup into the container. Use a measuring cup that marks ounces or that can be easily converted into ounces like cups. As you lift the measuring cup out of the ingredient, let it overflow from the top. You can even the measurement out later on. Use a knife to level off the measuring cup. Scrape the back of the knife over the top of the measuring cup to even out your measurement.
Level the ingredient off over the bowl or container so it can catch anything that falls off the top of the measuring cup. Part 2. Use a fluid measuring cup if you are handling a liquid.
The measuring cup used must be for fluid ounces if measuring a liquid. Dry cups will not give as accurate of a reading because they are designed to measure weight instead of volume.. Place the measuring cup on a flat, stable surface. Choose a measuring cup that measures in ounces or can be easily converted to it. Lay the cup on as even of a surface as possible, like a table. Avoid holding the cup in your hand while measuring, as the reading will be slightly off. Pour the liquid to approximately the desired line.
Fill the measuring cup until it reaches slightly underneath the level you are hoping to reach. Squat down until you are about eye level with the line to check your measurement, as looking from above can give you a warped measurement. Adjust the measurement until the bottom of the meniscus reaches the line. While measuring liquid ounces, you may notice that the top of the surface is not even and may curve along the edges.
This curve is called the meniscus. For the most accurate reading, the bottom not the top of the meniscus should reach the desired line. A cup or pint of ground meat or a vegetable would not provide an accurate measure. At home, we usually measure ingredients like flour and sugar using cups a unit of volume. Measuring flour and sugar by the cup is accurate enough for home kitchens.
Bakeries and other food manufacturing facilities, however, measure sugar and flour by weight to minimize the inherent differences in the ingredients from different sources and production batches.
I was really surprised the first time I saw eggs being measured by the gallon, but, in the food industry, the weight and volume of eggs could vary considerably depending on the size of the egg etc. OK, so you may be saying the old guy is on a tangent. What does all of this have to do with cleaning? Well, a lot actually.
This suggests that one avoirdupois ounce is approximately Similarly, we use two systems in measuring fluid ounces. For example, one unit of a fluid ounce is approximately Customary system while it is just approximately 28 ml. This makes one beg for the use of one unified, standard system of measurement which is not entirely applicable today. An ounce is measuring weight while a fluid ounce is measuring volume.
One pound is equal to 16 ounces while one pint is equal to 16 fluid ounces. One fl. Customary system. Cite APA 7 ,. Difference Between Fluid Ounces and Ounces.
