Solve Problems Involving Converting Measurements

In this activity, we're going to be solving problems involving calculating and converting different units of measure.

We'll be using mass, capacity, length, volume and time.

 

Information that will help - we need to know all of this information.

1,000 g = 1 kg

1,000 ml = 1 l

10 mm = 1 cm

100 cm = 1 m

1,000 m = 1 km

Volume is measured in cubic units (cm³, m³)

 

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

 

Let's look at an example of the type of question in this activity:

 

John has 1,200 ml of cola and 500 ml of lemonade.

What is the total amount of liquid in litres?

 

  

 

Answer

1,200 ml + 500 ml = 1,700 ml  

To convert from ml to l, we need to divide by 1,000 

1,700 ml ÷ 1,000 = 1.7 l (we don't need to include the last two zeros as they are not acting as place holders).

The total measure of liquid is 1.7 litres.

 

Now it's your turn - good luck!
