What is Capacity?

Capacity is the amount of liquid a container can hold. You've probably heard about it while filling a glass of juice or a swimming pool. It is also the amount of liquid called for in the ingredients of a recipe. It is an important concept that allows us to know how much liquid a container can hold or how much liquid is needed for something.

Common Units for Measuring Capacity:

• Milliliter (mL): This is applied to small liquid quantities. A glass of water or a bottle of soda may be measured in milliliters.

• Liter (L): This is applied to large quantities of liquids. For example, a milk jug or a bathtub might be measured in liters.

Understanding Converting Capacity

What is Conversion?

This process is known as conversion when one unit of measurement is changed to another. Generally speaking, for measurement of capacity, people often convert from liters to milliliters or vice versa since among all measuring units these are indeed the most frequently used to measure liquids.

To convert is like translating between two languages. Just as English and Spanish are two different languages, so are liters and milliliters. They are measures of the same liquid! But there is one rule that helps you know how to convert between them so you don't get confused.

How to Convert Capacity

There are two key conversions you will need to learn:

1. Conversion from Liters to Milliliters (L → mL)

When you are converting from liters (L) to milliliters (mL), you multiply by 1000.

1 liter (L) is equal to 1000 milliliters (mL).

So, in order to convert the liter into milliliters you multiply the number of liters by 1000.

Example:

If you have 2 liters (L) and you would like to know how many milliliters that is:

2 L × 1000 = 2000 mL

Then, 2 liters = 2000 milliliters   

2. From Milliliters to Liters (mL → L)

When going from mL to L you divide by 1000.

Why?

1 L = 1000 mL

Converting milliliters into liters functions by taking the number of milliliters divided by 1000.

How does this function?

You have 5000 mL and want to know how many litres that is

5000 mL ÷ 1000 = 5 L

5000 mL = 5 L

Steps in Changing Capacity

Convert from Liters to Milliliters:

• Step 1: Identify the number you wish to convert in liters.

• Step 2: Multiply that number by 1000.

• Step 3: Write the result in milliliters (mL).
  
  

Example:

Convert 3.5 liters to milliliters.

3.5 L × 1000 = 3500 mL

3.5 liters = 3500 milliliters.

Converting from Milliliters to Liters:

• Step 1: Identify the number of milliliters you want to convert.

• Step 2: Divide that number by 1000.

• Step 3: Write the result in liters (L).
  
  

Example:

Convert 1200 milliliters to liters.

1200 mL ÷ 1000 = 1.2 L

1200 milliliters = 1.2 liters.

Why Do We Need Conversion?

Conversions are useful because liquids are measured in different amounts depending on the container and situation.

For example, while shopping at the store, you may find a large jug of milk labeled as 2 liters, but in a recipe, you need to use only 500 milliliters of milk. Conversion and how much milk you will have is quite easy.

Some More Examples of Capacity Conversion:

• You have a bottle of water with 0.75 L. How many milliliters is that?

0.75 L × 1000 = 750 mL

So, 0.75 liters = 750 milliliters.

• You need 250 milliliters of juice to make a recipe. How much is that in liters?

250 mL ÷ 1000 = 0.25 L

Thus, 250 milliliters = 0.25 liters.

• You have a large water jug that can contain 5 liters. How much water can it contain in milliliters?

5 L × 1000 = 5000 mL

Thus, 5 liters = 5000 milliliters.

How to Convert Capacity:

From Liters to Milliliters:

To convert from liters to milliliters, multiply by 1000 since there are 1000 milliliters in 1 liter.

For example:

If you have 3 liters (L), you multiply:

3 L × 1000 = 3000 mL

Thus, 3 liters = 3000 milliliters

Milliliters to Liters:

To convert from milliliters to liters, divide by 1000 since there are 1000 milliliters in 1 liter.

For example:

If you have 5000 milliliters (mL), you divide:

5000 mL ÷ 1000 = 5 L

So, 5000 milliliters = 5 liters.

By mastering capacity conversions and operations, you can seamlessly manage resources – whether it's filling bottles or optimizing production lines!

Operations with Capacity:

We commonly have to add, subtract, multiply, or divide when we are working with capacity in real life like cooking, filling up a pool, or while doing a science experiment.

1. Addition:

Add the numbers together when you are adding liquids that are in the same unit.

You have 200 mL of juice in one cup and 500 mL in another cup.

200 mL + 500 mL = 700 mL

So, in total, it is 700 milliliters.

2. Subtraction:

You apply subtraction when you want to know how much liquid is left inside the container after pouring or using a portion of it.

Exercise:

You have a bottle of 2-liter capacity. You have drank 500 milliliters (mL) from it. What do you still have?

2 L = 2000 mL

2000 mL - 500 mL = 1500 mL

And 1.5 L is still left in the bottle.

3. Multiplication:

Multiplication is useful when there are many containers which are identical in size, and you need to find how much total capacity. (Check more multiplication here)

Example

There are 5 bottles, each can hold a liter of water.

5 × 1 L= 5 L

So the combined volume of the five bottles is 5 liters

4. Division:

You can split it up if you have a large amount of liquid by the number of servings you want.

Lemonade

You have 10 litres (L) of lemonade and wish to pour it equally into 4 tins.

10 L ÷ 4 = 2.5 L

Thus, each of your tins will receive 2.5 liters of lemonade.

Fun Fact

Here's a fun fact that might help you place this in perspective, just how massive capacity really is:

The biggest bottle of soft drink ever produced was around 9,500 liters. This was a giant Coke bottle, weighing as much as a car and meant for some special event!

Real Life Applications of Capacity

1. Cooking and Baking:

Most recipes contain liquid ingredients, such as milk, water, or oil. For example, a cake recipe will tell you to use 250 mL of milk or to boil pasta in 1 liter of water.

Measuring cups usually indicate gradations in milliliters (mL) and liters (L), so you will know exactly how much liquid to use.

2. Hydration or Water Intake: 

Hydration is very important, and water bottles are sold in various volumes. A small water bottle could be 500 mL, and a large one could be 1.5 L or 2 L of water.

Your intake should be fairly high because water is very important for maintaining health, and knowing just how much you are drinking really helps!

3. Tank Filling Up:

Cars and motorcycles have tanks in them, as do even your bicycle's water bottle, in which we use capacity to measure how much liquid they will need, the amount of gas a car fuel tank can hold is 40 L, and the watering can that one might use on plants might hold 2 L.

4. Sports and Swimming Pools:

Swimming pools have large capacities, measured in thousands of liters. For example, a small family swimming pool contains an amount of water equivalent to about 5,000 liters, while an Olympic swimming pool can hold about 660,000 liters of water. That's enough to fill a lot of bathtubs!

5.Storage and Containers:

One of the necessary considerations while making a choice over storage containers would include capacity-though not restricted to food and liquids, as well as other materials. For example, when you buy a storage jar in the kitchen, it might contain 1 liter of rice or 500 mL of jam. The same goes for big containers, such as trash bins, water tanks, or industrial storage silos, with varying quantities of materials according to their size. Knowing the several types of capacity helps select the right container for the amount needed.
