Answer:
In this activity you will convert between metric
units of length:
kilometres, metres, centimetres, and millimetres.
1 km = 1000 m
1 m = 100 cm
1 m = 1000 mm
1 cm = 10 mm
Think about
how to change from one unit to another.
A kilometre is one thousand metres! so km m
or m km
A millimetre is a thousandth of a metre! so mm m
or m mm
A centimetre is one hundredth of a metre! so cm m
or m cm
Think about
how to use this to help you change to different units … and back again ….
mm cm m km
mm cm m km
1000
÷ 1000
÷ 1000
1000
÷ 100
100
÷ 10 ÷ 100 ÷ 1000
10 100 1000
