Conversion of Length

Conversion of Metres into Centimetres

Example : Convert into centimetres (cm).

a. 6 m b. 30 m c. 4 m 56 cm

d. 14 m 19 cm e. 25 m 9 cm f. 32 m 45 cm

Solution : a. 6 m b. 30 m

6 × 100 cm 30 × 100 cm

= 600 cm = 3000 cm

c. 4 m 56 cm d. 14 m 19 cm

4 × 100 cm + 56 cm 14 × 100 cm + 19 cm

= 400 cm + 56 cm = 1400 cm + 19 cm

= 456 cm = 1419 cm

e. 25 m 9 cm f. 32 m 45 cm

25 × 100 cm + 9 cm 32 × 100 cm + 45 cm

= 2500 cm + 9 cm = 3200 cm + 45 cm

= 2509 cm = 3245 cm
