Just a quick exercise in converting metric units from small to large and vice versa. This is not easy and as stated before a good understanding of both the metric system and place value is needed to be able to do this.
It is probably easier to convert large units to smaller:
Eg 3.5 litres = 3 500 ml
Converting small to large can bring problems with place value
Eg 740 cm = 7.4 metres or 7.40 metres. Either is correct.
By now children should know all the facts about the metric system and there is not a lot of point in attempting this if they don’t.
