Basics on the topic Capacity
In This Capacity Video for 4th Grade
Zuri and Freddie are contestants on the show, Extreme Cake Bake.The bakers are going to make a cake replica of their van. In order to make the most extreme cake, Zuri and Freddie will need to know the customary units of capacity.
What is Capacity?
Capacity is the amount that a container can hold. It’s a word we use to describe when the space is empty. We have different measurements for capacity depending on the size.
What are Units of Capacity?
These are the different measurements we use. The measurement used depends on the size of the container needed. As we need to hold more in a container, we change the unit of measurement.

“Let’s welcome our next bakers to the competition." "Straight from the landfill... it's Zuri and Freddie!!!" “Tell us what you will be baking.” “We will be making a triple berry cake in the shape of our van.” “Wow! That DOES look EXTREME!” “ Ok, bakers, you have seven hours and all the supplies you need." “ Your time begins NOW” In order to make the most extreme cake, Zuri and Freddie will need to know the customary units of “Capacity”. Capacity is the amount that a container CAN hold. It is a word we use to describe when the space is empty. In the United States, we call these measurements the customary units of capacity... such as fluid ounces... cups... pints... quarts... and gallons. The measurement used depends on the size of the container needed. As we need to hold more in a container,... we change the unit of measurement. We use these units of measurement in many parts of life... However, cooking or baking are the most common places you will see these measurements used. Let's take a look in at Zuri and Freddie's cake baking skills to help us understand the measurements. The smallest unit of measurement is fluid ounces. We use this unit to measure liquids that we need a very little amount of. The vanilla and food coloring would be measured in fluid ounces... and contained in tablespoons or in droppers. Once we need more than eight fluid ounces, we use a container that can hold a greater amount or has a higher capacity. This unit is called a cup. The cup is the most commonly used unit of measurement for capacity. In recipes, when we need items like milk and cooking oil, we use cups to contain our ingredients. We can fill the cup many times when we need several units. As the amounts of ingredients increase, our units of capacity continue to change. The next unit is called a pint. A pint is the same amount as two cups. Berries come in a container called a pint. Quarts are the next unit we use for capacity. Quarts are used when need to hold the same amount as two pints or four cups. A mixing bowl and a baking pan are measured in quarts. The largest unit for capacity is called gallons. Gallons are used when we need to hold the equivalent amount of four quarts. Larger quantities of milk come in gallons. With only seconds left in the competition, let's review the customary units of measurement. Remember... capacity is the word used to describe the most a container can hold. We have different measurements for capacity depending on the size. In the United States, we call these measurements the customary units of capacity. These units are... fluid ounces... cups... pints... quarts... and gallons. "BAKERS, YOUR TIME IS UP!" "Let's take a look at your results!!"
What is the amount of space inside a container called?Hints
Remember, what are cups used to measure?
Length measures distance, so it is not the amount of space inside a container.Solution
The maximum amount a container can hold is called the capacity.
*Length- measures distance
*Containers- used to hold things
*Gallons- a unit used to measure capacity
Sort the customary units of capacity.Hints
Put the smallest unit of capacity at the top and the largest unit of capacity at the bottom.
Use the image above to help visualize the different units of capacity.
1 fluid ounce is the smallest and 1 gallon is the largest.
1 cup is smaller than 1 pint.Solution
The customary units of capacity are:
- Fluid ounces
Which unit of measure is best?Hints
Approximately means close to that amount but not always the exact amount.
If objects are small it is likely they are less than 1 cup.
1 cup is about the size of a drinking glass.Solution
- A bottle of water is a little greater than 1 cup.
- A gallon of milk is equal to 1 gallon.
- A spoon full is about 1 fluid ounce.
- A small shampoo container is slightly greater than 1 cup.
- A pitcher of juice is a little greater than 1 gallon.
Select the statements that are correct.Hints
Read each answer choice carefully. You will need to select more than one.
There are 4 correct statements.
Use this image to help visualize the different sizes to measuring capacity.Solution
✅ A gallon is larger than a cup.
✅ A pint is larger than a fluid ounces.
❌A pint is smaller than a cup.
✅ A cup is larger than a fluid ounce.
❌A quart is smaller than a pint.
✅ Capacity measures the space inside of a container.
Matching containers to units.Hints
The largest container matches with the largest unit of capacity.
The smallest container matches with the smallest unit of capacity.Solution
The unit of capacity matches the container based on the sized of the container. The larger container gets the larger unit and the smaller container gets the smaller unit.
Match the units of measurement to the amounts shown.Hints
Since a cup is bigger than a fluid ounce, we will need multiple fluid ounces to make a cup!
When you buy milk in a store, getting four quarts is the same as buying one gallon!Solution
8 Fluid Ounces = 1 Cup
2 Cups = 1 Pint
2 Pints = 1 Quart
4 Cups = 1 Quart
4 Quarts = 1 Galloon
