Example 6

1. Convert 340mℓ to ℓ.

1ℓ =1000mℓ to change from mℓ to ℓ divide by 1000

340 mℓ: 340 ÷ 1000 = 0, 34ℓ

2. If the volume of the car tank is 70 000 cm , how many litres of petrol can it
hold?

This can be done in two ways:

3
3
First option: convert cm to m
3
3
1m = 1 000 000 cm
This means you divide by 1000 000

3
70000÷1000000 = 0, 07m
3
Convert m to ℓ
3
1m = 1000ℓ

This means you multiply by 1000

0, 07 x 1000 = 70ℓ

3
Second option: convert cm to m ℓ
3
1cm = 1mℓ

This means you multiply by 1

70000 x 1 = 70 000mℓ

Convert mℓ to ℓ

1 ℓ = 1000mℓ

This means you divide by 1000

70 000 ÷ 1000 = 70ℓ

When working out the volume of different containers, kℓ will be used for larger
quantities, while ml is used for smaller containers.
