Milli means 1,000 times smaller
Kilo means 1,000 times larger

Keywords

Metre (m) and millilitre (ml) - A millimetre (mm) is a metric measure of distance used for small lengths. The basic unit of length (or distance) in the metric system is metre (m)
Kilometre (km) and metre (m) - A kilometre (km) is a metric measure of distance.
Kilogram (kg) and gram (g) - A kilogram is a measure of mass, equivalent to one thousand grams.
Litre (l) and millilitre (ml) - A litre is a measure of capacity, equivalent to one thousand millilitres.

Common misconception

Pupils may miscalculate measures questions involving unit conversions if they are not secure with the key conversions of 1 m = 1,000 mm, 1 km = 1,000 m, 1 kg = 1,000 g and 1 l = 1,000 ml.

Spend time discussing the etymology of the words so pupils are not necessarily relying on memory and can figure out the equivalences if they cannot recall them. 'Milli' means 'thousandth' and 'kilo' means 'thousand': both relate to a thousand parts.

Give quickfire opportunities outside Maths lesson to recall these key conversions. Present measures in contexts which are accessible to the children and, where possible give practical opportunities for them to experience the measurements and build reference points for length, mass and capacity.
