    Metres and Centimetres into Centimetres

                To convert metres and centimetres into centimetres, multiply the number of metres
                by 100 and add the product to the number of centimetres.

                examples:  a.  9 m 25 cm = (9 × 100) cm + 25 cm = 900 cm + 25 cm = 925 cm
                               b.  16 m 72 cm = (16 × 100) cm + 72 cm = 1600 cm + 72 cm = 1672 cm

                Kilometres into Metres

                To convert kilometres into metres, multiply the number of kilometres by 1000.

                examples:  a.  3 km = (3 × 1000) m = 3000 m                    b.  5 km = (5 × 1000) m = 5000 m

                Kilometres and Metres into Metres

                To convert kilometres and metres into metres, multiply the number of kilometres by

                1000 and add the product to the number of metres.

                examples:  a.  9 km 265 m = (9 × 1000) m + 265 m = 9000 m + 265 m = 9265 m
                               b.  8 km 490 m = (8 × 1000) m + 490 m = 8000 m + 490 m = 8490 m

                            Exercise 9B

                    1.  Convert the following into cm.

                        a.  4 m =                      cm              b.  14 m =                       cm

                        c.  26 m =                       cm            d.  5 m 10 cm =                         cm

                        e.  95 m 8 cm =                        cm      f.   12 m 18 cm =                       cm

                        g.  45 m 75 cm =                        cm

                    2.  Convert the following into m.

                        a.  5 km =                       m             b.  6 km =                       m

                        c.  9 km =                       m             d.  4 km 300 m =                          m

                        e.  2 km 500 m =                         m     f.   6 km 15 m =                       m

                        g.  1 km 425 m =                        m
