A kilometer is a unit of length in the metric system of measurement that is equal to 1000 meters.
To show how far 1 kilometer is, we can use the length of an Airbus 747.
The length of an airbus 747 is about 76 meters.
1000 meters / 76 meters =13.15
Therefore, 1 kilometer is approximately the length of 13 Airbuses 747.
The length of some cruise ships is about 330 meters. 1000 meters /330 meters is 3.03.
Therefore, 1 kilometer is about the length of 3 cruise ships if each cruise ship has a length of 330 meters.
