Key Stage 2
Meaning
A centimetre is a distance the same as 10 millimetres.
About Centimetres
- There are 100 centimetres in one metre.
- There are 10 millimetres in one centimetre.
- A thumb nail is about 1 centimetre long.
- A mouse is around 15 centimetres long.
Key Stage 3
Meaning
A centimetre is a unit of distance equivalent to 1/100th of a metre.
About Centimetres
- Centimetres are shortened to cm with a lower case c and a lower case m.
- Centimetres are for the length, width and height of everyday objects.

Key Stage 4
Meaning
Centimetres (cm) are a unit of distance, displacement and wavelength 100 times smaller than the SI Unit; the metre.
About Centimetres
- Centimetres are shortened to cm with a lower case c and a lower case m.
- Centi means one hundredth so there are 100 centimetres in a metre.
