We are learning to convert units of length.
10mm = 1cm
÷ 10
÷ 100
÷ 1000
100cm = 1m
mm
1000m = 1km
cm
x 1000
m
x 1000
km
x 1000
Remember: mm are smaller than cm so you will need a lot more of them to make up the equivalent length.
E.g. 54cm = 540mm
Try converting the following lengths from mm to cm.
1) 345mm =
cm
2) 465mm =
cm
3) 3641mm =
cm
4) 14mm =
cm
Now try converting the following cm to mm.
1) 12.5cm =
mm
2) 641cm =
mm
3) 7445cm =
cm
3) 70.3m =
mm
4) 6987.8cm =
mm
4) 3540m =
cm
Now try converting the following m to cm.
1) 20m =
cm
2) 63.1m =
cm
