LENGTH - THE KILOMETRE (Km)
The unit Kilometre is used to measure big lengths and long distances. In writing, we use Km as Kilometre.
1 Km = 1000 m
Example 1 : Convert 3482 m into Km and m.
Solution : We know that 1 km = 1000 m
                 So,          3482 m = 3000 m + 482 m
                                             = 3 km + 482 m.
Example 2 : Convert 1008 m into km and m.
Solution : 1008 m = 1000 m + 8 m = 1 km + 8 m.
Example 3 : Convert 1 km 27 m into m.
Solution : 1 km 27 m = 1000 m + 27 m = 1027 m.
Example 4 : Convert 5 km 4 m into m.
Solution : 5 km 4 m = 5000 m + 4 m = 5004 m.
