Depending on the recipe, ounces can be a measurement of volume or weight. Fluid ounces are a measurement of volume, whereas dry ounces are a measurement of weight. As long as the ingredient is measured carefully, dry or liquid measuring cups should give you a simple and accurate calculation. For the most precise reading, use a kitchen scale to measure your ingredient.

### Using a Kitchen Scale

1. 1

Weigh the cup on a kitchen scale to check your measurements. After you have leveled off the cup, it should be accurate. But if you want a more precise measurement, place the cup on a kitchen scale that can measure in ounces. Compare the scales reading to your initial measurement to determine how accurate your measuring cup is.[1]

2. 2

Zero out the measuring cups weight. Place the empty measuring cup on the scale before you fill it with the ingredient. This will allow you to get the exact measurement of the ingredient in ounces. If you have a digital scale, hit the on or clear button to zero out the weight.[2]

• If you have an older, mechanical scale, turn the knob back to the zero mark after placing the measuring cup on it.
• For balance scales, set the pointer to the center mark.
3. 3

Fill the measuring cup with the ingredient and place it on the scale. Lift the measuring cup off of the scale and add the ingredient you want to measure. Adjust the ingredient amount by adding or removing until it reaches the desired amount of ounces.

• Make sure the scale is set to ounces before measuring your ingredient.
4. 4

Weigh each ingredient separately if weighing multiple items. Use different measuring cups to keep the ingredients separate. Remember to zero out each cup before recording the ounce measurement for the most precise reading.

### Calculating Fluid Ounces

1. 1

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..[3]

2. 2

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.
3. 3

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.[4]

4. 4

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.[5]

### Measuring Dry Ounces

1. 1

Use dry measuring cups for solid ingredients. 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.

2. 2

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.[6]

3. 3

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.[7]

4. 4

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.[8]

• Any utensil with a straight, flat edge (like a spatula) can be used as an alternative to a knife.

Not necessarily. An ounce can be either a measure of weight or a measure of volume (like a cup or a milliliter). A fluid ounce (fl oz) is a volume measurement, usually used for measuring liquids. However, sometimes people will simply say or write â€œounce/ozâ€ without the fluid/fl when theyâ€™re talking about fluid ounces. So, check the context to figure out which is more likely. For instance, 1 oz of milk is likely a fluid ounce, while 1 oz of garlic would probably be a weight measurement.

One ounce is approximately 0.0295735 of a liter. There are about 33.814 ounces in a liter.

• Question

How many ounces are in a 2 L bottle?

67.628 according to conversion rates with liquid ounces instead of solid ounces, since liters are commonly used to measure liquid.

• Question

What does oz mean in measuring?

Andy Winder

Oz stands for ounces. For example, if a recipe calls for 6 oz of butter, it is asking for 6 ounces.

• Question

I have an 18 oz jar of apple jelly and I need only 5 oz for a recipe. How do I measure this?

There are 8 oz in a cup, so 4oz/8oz + 1oz/8oz = 1/2 cup + 1/8 cup (or 2 tablespoons).

• Question

How many ounces are in 2 liters?

67.628 according to conversion rates with liquid ounces instead of solid ounces, since liters are commonly used to measure liquid.

## Tips

• If you have a measuring cup or scale that uses pounds or grams, both can easily be converted to ounces.

To measure ounces, select either a liquid or dry measuring cup. If youâ€™re measuring a liquid, place the measuring cup on a flat surface and pour the liquid into the cup. Be sure to bend down to view the measurements on the side of the cup. Make sure the liquid reaches the right measurement. For a dry ingredient, use the measuring cup to scoop out the ingredient. If the cup is overflowing, scrape a knife across the top to level it.
