Free Y4 maths worksheet: using standard units

Well, the metric system has been with us for a long time but there are still many children who use Imperial units when talking, often not knowing very much about them. Schools teach the metric system: society seems to want to keep the old fashioned system and it is our children who suffer.

Metric is far easier and this worksheet reminds children of the main units:

1 km = 1000 m

1 m = 100 cm

1 cm = 10 mm

1 kg = 1000 g

1 litre = 1000 ml

It is also worth reminding ourselves that a litre of water has a mass (weighs) one kilo and fits exactly into a 10 cm cube!
