Converting millimetres and centimetres
Measure this line in mm then in cm. What do you notice?
_______ mm
_______ cm
Now convert these millimetre lengths to centimetres
30mm =
cm
100mm =
cm
50mm =
cm
120mm =
cm
70mm =
cm
150mm =
cm
90mm =
cm
200mm =
cm
Convert these centimetre lengths to millimetres
1cm =
mm
11cm =
mm
4cm =
mm
14cm =
mm
6cm =
mm
22cm =
