Measuring in millilitres

Home learning focus

Learn how to estimate and measure volume and capacity in millilitres.

This lesson includes:

  • two worksheets
  • one activity


We use millilitres and litres to measure volume and capacity.

Capacity is the amount of liquid a container can hold.

Volume is how much liquid is in the container.

We can write l for litre and ml for millilitre.

Now let's look at some containers with different scales. Can you spot what volume of liquid is in each container below?

For the last question, you will need a measuring jug to put your measuring skills to the test!

A measuring jug containing 100 millilitres of mouthwash. The scale on the jug is counting up in 100 millilitres. The jug has a capacity of 300 millilitres.

What volume of mouthwash is in the container? Can you see what the scale is counting up in?

Activity 1

Measurement detective

Be your own measurement detective and work with a parent or guardian to find objects around your home which hold up to 1 litre, for example a bottle of water or a can of orange juice.

  • Can you find a container that holds exactly 500ml?
  • Can you find a container that holds exactly 1l?
  • Which container holds the most?
  • Which container holds the least?

Activity 2

Colour the measuring jug

Colour each jug to show the correct volume. Can you circle the jug that contains the most liquid? The correct answers are on page 2 of the worksheet.
