2. Length
Metric measurements are millimetre (mm) centimetre (cm), metre (m) and kilometre (km)
10 mm = 1 cm
100 cm = 1 m
1000 m = 1 km

3. To change cm into millimetres we multiply by 10
Example
Change the following cm into mm.
4 cm
4.3 cm
9.6 cm
23cm
18.7 cm
= 40 mm
= 43 mm
= 96 mm
= 230 mm
= 187 mm
To change cm into millimetres we multiply by 10

4. To change millimetres into centimetres we divide by 10
Example
Change the following mm into cm.
70 mm
86 mm
4 mm
130 mm
263 mm
= 7 cm
= 8.6 cm
= 0.4 cm
= 13 cm
= 26.3 cm
To change millimetres into centimetres we divide by 10

5. To change metres into centimetres we multiply by 100
Example
Change the following m into cm.
5 m
4.6 m
3.14 m
15 m
6.07 m
= 500cm
= 460cm
= 314cm
= 1500cm
= 607cm
To change metres into centimetres we multiply by 100

6. To change centimetres into metres we divide by 100
Example
Change the following cm into m.
700cm
630cm
84cm
1250cm
316cm
= 7 m
= 6.3 m
= 0.84 m
= 12.5 m
= 3.16 m
To change centimetres into metres we divide by 100

7. To change kilometres into metres we multiply by 1000
Example
Change the following km into m.
3 km
2.7 km
0.84 km
5.623 km
618.2 km
= 3000 m
= 2700 m
= 840 m
= 5623 m
= m
To change kilometres into metres we multiply by 1000

8. To change metres into kilometres we divide by 1000
Example
Change the following m into km.
3000 m
4700 m
5062 m
824 m
18300 m
= 3 km
= 4.7 km
= km
= km
= 18.3 km
To change metres into kilometres we divide by 1000
