### QUESTION 1 of 10

Well done, you have decided to practice for the SATs Maths test!

In this activity, we will recap on how to convert between units of measurement.

How do we convert between metric units of measurement?

Firstly, it will really help if you can remember these key facts:

• 10mm = 1cm
• 100cm = 1m
• 1000m = 1km
• 1000g = 1kg
• 1000kg = 1 tonne
• 1000ml = 1 litre
• 100cl = 1 litre​

And then these key points when converting...(you see it's all in the place value!)

Now, time to have a go at some practice questions!

Match the appropriate unit of measure for each item below.

## Column B

Weight of an elephant
g
Weight of an apple
km
Length of a park
cm
Length of a book
tonnes

1000 gallons

13,000 litres

18,000-20,000 gallons

10,000-11,000 millilitres

1000 gallons

13,000 litres

10,000-11,000 millilitres

1000 gallons

13,000 litres

18,000-20,000 gallons

13,000 litres

18,000-20,000 gallons

A small cake weighs 102 g.

How much would 24 cakes weigh?

10,000-11,000 millilitres

1000 gallons

13,000 litres

18,000-20,000 gallons

Look at the recipe below to make a pizza and write the total weight of the ingredients in g and kg.

200 g plain flour

7 g dried yeast

5 g sugar

100 g mozzarella

10 g basil

10,000-11,000 millilitres

1000 gallons

13,000 litres

18,000-20,000 gallons

• Question 1

Match the appropriate unit of measure for each item below.

## Column B

Weight of an elephant
tonnes
Weight of an apple
g
Length of a park
km
Length of a book
cm
EDDIE SAYS
Did you get the hang of the first question? The units of measure were given in an abbreviated form, for example, kilograms = kg. When answering a question like this, use your common sense and think logically about the size of each object.
• Question 2

Choose how much water a swimming pool would hold.

18,000-20,000 gallons
EDDIE SAYS
Did you spot that a swimming pool holds between 18,000- 20,000 gallons of water? When choosing the answer, think carefully about what each unit of measure means, 10,000-11,000 millilitres is the same as 10-11 litres, this is the same as 10-11 big bottles of coke, definitely not enough to fill a pool!
• Question 3

1 kg = 1000 g

1000 kg = 1 tonne

EDDIE SAYS
Nice job if you wrote 4kg! 1000g = 1kg. We have to divide 4000g by 1000 to find the answer. You have made a super start- keep it up!
• Question 4

1 kg = 1000 g

1000 kg = 1 tonne

EDDIE SAYS
Brilliant job if you wrote 9.5 kg! 1000 g = 1 kg. We have to divide 9500 g by 1000 to find the answer. This time, we have an answer with a decimal place to represent the 500 g from 9500 g.
• Question 5

1 kg = 1000 g

1000 kg = 1 tonne

EDDIE SAYS
Don't worry if you found that tricky! This time we have to multiply 6.02 kg by 1000 to convert it to g. 6.02 kg x 1000 = 6020 g
• Question 6

1 kg = 1000 g

1000 kg = 1 tonne

EDDIE SAYS
Phew, that was a challenge! To convert kg to tonnes, we have to divide by 1000. 2784 kg ÷ 1000 = 2.784 Wow, you have just practised a lot of conversions using weight or mass- well done!
• Question 7

10 mm = 1 cm

100 cm = 1 m

1000 m = 1 km

EDDIE SAYS
Phew, that was a toughie! Remember to refer to the key facts when completing this type of conversion and think carefully about the place value of each digit- how many places do we need to move each one? When we convert mm to cm, we divide by 10. When we convert m to km, we divide by 1000. When we convert cm to m we divide by 100. When we convert km to m we multiply by 1000 This will get easier the more you practice!
• Question 8

A bottle of shampoo holds 100 ml.

How many bottles can be filled using two litres of shampoo?

EDDIE SAYS
How did you find this calculation? Step 1: Convert 2 litres to ml =2 x 1000 = 2000 ml Step 2: Divide 2000 by 100 = 20 So, 2 litres will be able to fill 20 bottles of shampoo You are making great progress and only have two questions left, keep it up!
• Question 9

A small cake weighs 102 g.

How much would 24 cakes weigh?

EDDIE SAYS
Great job if you wrote 2.448 kg How to solve: Step 1: 102 g x 24 = 2448 g Step 2: Convert to kg, 2448 ÷ 1000 = 2.448 kg
• Question 10

Look at the recipe below to make a pizza and write the total weight of the ingredients in g and kg.

200 g plain flour

7 g dried yeast

5 g sugar

100 g mozzarella

10 g basil

EDDIE SAYS
Don't be afraid to give it a go! When added together, all of the ingredients total 322 g. To convert this to kg, we divide by 1000, which gives us the answer of 0.322 kg We hope you've improved your knowledge on metric measures, keep up the great work!
