Measurements are vital processes we do in various aspects of our lives, especially in cooking.

If you want to use a recipe for making food or baking, you’ll need cups with metric marks, either in ounces or tablespoons, to narrow down the quantity of flour, water, etc.

Speaking of ounces and measurements brings us back to the topic: how many ounces are there in a 1/3 cup?

There are 2.78 fluid ounces in 1/3 cups. Such measurement cups make using recipes for cooking easy as you don’t have to stress about putting too much water or dry food items. You only have to measure them in such cups and check they’re in the same range as the measurement grades.

How to Measure Ounces in a ⅓ Cup?

Measuring ounces in a one-third cup is easy. You only have to pour in the content and watch the content poured into the cup.

Then, once it reaches the 1/3 mark, you can stop. Also, note that a one-third measurement equals five tablespoons & one teaspoon in a cup.

Measuring ounces differ between dry and liquid items, and there are guidelines to help you achieve precise measurements of dry and fluid ounces in a cup.

#1. Dry Ounces in 1/3 Cups

Generally, 1/3 cups contain 2.66 ounces of content, but this might not be the same quantity for liquid and dry ingredients due to the contrasting properties of their physical elements.

Hence, you must understand the correct amount of ingredients to use to make a perfect recipe.

Fill in the dry ingredients to the 1/3 mark of a measurement cup and use a spoon to flatten it.

This technique is practical because dry ingredients can increase in content by overspreading, making you believe they’ve come up to the 1/3 mark, which is false.

After leveling it, you may see a need to make changes by either adding more ingredients or removing some.

You can also measure them in tablespoons; 1/3 equals 5 1/3 tablespoons in a cup or 2.6 ounces.

Or you could measure in grams with 1/3, meaning 75.6 grams or 5 1/3 tablespoons in a cup.

#2. Liquid Ounces in 1/3 Cups

A one-third cup has 2.78 cups of fluid ounces.

The perfect method for obtaining a correct measurement is keeping the container at your eye position to attentively inspect if the liquid ingredient is in the appropriate spot of the measurement marking or not.

Why Are Only 2.78 (~ 2 3/4) Ounces in a ⅓ Cup?

The ounce content (2.7) follows the American measurement system.

Generally, it is recognized that one cup contains eight ounces, so you’ll measure the 1/3 cup with the standard eight ounces in a cup.

One cup (eight ounces) or tablespoons and one teaspoon equal 1/3 giving 2.78 after calculations.

1/3 of a cup means the one-third section of a cup, just like a half section.

For instance, to obtain a 1/4 segment implies dividing a cup’s content into four uniform parts; remove one, and three will remain.

However, remember that the ounces differ according to the physical properties of measured ingredients. Only fluid ounces have 2.78 ounces or 78. 8 grams.

You can use a gram or tablespoon of 1/3 cup to determine the measurement of both dry and fluid ingredients before using them to achieve a perfect recipe.

However, the weight of dry ingredients plays a huge role in this ounce contrast, so it isn’t advisable to solely depend on the oz conversion.

Can You Measure Ounces in a ⅓ Cup of Water Without Measuring the Cup?

You can follow other easy steps to ensure the fluid ounces in a cup of water.

For instance, size comparison, kitchen scales, and tablespoons & teaspoons of a cup of water measurement.

Size Comparisons

There are four strategies to follow the size comparison method; they include:

#1. Objects as References

You can refer to objects as visual aids by likening the cup measurements to items of equal sizes. For example, a teaspoon is compared to a fingertip in size, while a tablespoon is compared to ice cubes, etc.

#2. Use a Transparent Vessel

This technique requires you to use your visual aids to imagine the cup measurement of 1/3 cup.

You already know that 1/2 means half of a glass, and half a cup of water is like a tennis ball, so you can use a wide glass cup to carry out this method.

A half glass of water is more than one-third cup of water. Following this process makes the work easier.

You can pour water into a glass until it reaches its center, which is half, and then reduce it. Then, view it at eye level and confirm if it looks just right.

#3. Kitchen Scale

Using a kitchen scale to measure 1/3 ounce of a cup of water is alright, but remember to calculate the water’s weight.

1/3 weighs 78.9 grams and 2.7 ounces, so use this metric while measuring.

Pick any cup and position it in the middle of the kitchen scale when it is still empty to get the cup’s weight and eliminate it from the readings.

Or you could set the scale to remove the container’s weight and put it to zero to give you a precise reading.

Then, slowly pour the water into the container to monitor the weight as it changes and ensure you don’t exceed what is needed.

#4. Use Tablespoons and Teaspoons

Remember that 1/3 cup of fluid ounces equal to five tablespoons & one teaspoon of a cup containing one-third liquid.

Hence, you can simply measure these stipulated tablespoons and teaspoon of water to a container to achieve that measurement without measuring the cup.

Carefully pour water into the tablespoon to prevent spillage and transfer it to the glass; do this repeatedly until you reach the number of times.

You could commit this simple strategy to mind to avoid going through all that stress some other time or use a marker to specify the measurement of the 1/3 cup of water on the container you used.

Can We Measure Water by Ounces or by Cup Size?

You can accurately measure water by fluid ounces of measurement markings in a cup.

However, using cup sizes will not give reliable results as their sizes only range from small and medium to large.

For example, it doesn’t supply a precise measurement if a glass of water is eight ounces (one cup) or 16 ounces (two cups), etc., and you need 1 2/3 cup.

Measuring water by ounces gives you the volume of the water, which is a correct method than cups. However, do remember that ounces and fluid ounces are an exception to water.

Both measurement units are used for different ingredients and are barely used for similar contents.

For instance, a cup of wheat and gravy sauce fills up the same volume, but their weights contrast with each other.

The wheat flour is around four ounces, while the tomato sauce weighs approximately eight ounces.

This difference indicates that it isn’t reliable to interchange the fluid ounce and ounce, particularly regarding water.

A straightforward explanation of the difference between a fluid ounce and ounce is that the former is for volume while the latter is for weight.

A rule to remember when measuring water is to hold them at eye level during measurement.

It might be better to allow someone else to pour the water into the measuring cup while you bend to assume a uniform position with the measuring cup.

This way, you will see everything before the water goes above the 1/3 mark. The water’s level should be precisely on the spot; it shouldn’t be more than or below.
