Metric Units 12 June 2021

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

Example Change the following cm into mm. (i) 4 cm = 40 mm (ii) 4. 3 cm = 43 mm (iii) 9. 6 cm = 96 mm (iv) 23 cm = 230 mm (v) 18. 7 cm = 187 mm To change cm into millimetres we multiply by 10

Example Change the following mm into cm. (i) 70 mm = 7 cm (ii) 86 mm = 8. 6 cm (iii) 4 mm = 0. 4 cm (iv) 130 mm = 13 cm (v) 263 mm = 26. 3 cm To change millimetres into centimetres we divide by 10

Example Change the following m into cm. (i) 5 m = 500 cm (ii) 4. 6 m = 460 cm (iii) 3. 14 m = 314 cm (iv) 15 m = 1500 cm (v) 6. 07 m = 607 cm To change metres into centimetres we multiply by 100

Example Change the following cm into m. (i) 700 cm = 7 m (ii) 630 cm = 6. 3 m (iii) 84 cm = 0. 84 m (iv) 1250 cm = 12. 5 m (v) 316 cm = 3. 16 m To change centimetres into metres we divide by 100

Example Change the following km into m. (i) 3 km = 3000 m (ii) 2. 7 km = 2700 m (iii) 0. 84 km = 840 m (iv) 5. 623 km = 5623 m (v) 618. 2 km = 618200 m To change kilometres into metres we multiply by 1000

Example Change the following m into km. (i) 3000 m = 3 km (ii) 4700 m = 4. 7 km (iii) 5062 m = 5. 062 km (iv) 824 m = 0. 824 km (v) 18300 m = 18. 3 km To change metres into kilometres we divide by 1000
