About Kilometre and Centimetre
A kilometre is 1,000 metres, the standard metric unit for longer distances. It is used for road distances, running races and geography almost everywhere outside the United States and the United Kingdom.
A centimetre is one-hundredth of a metre, or 10 millimetres. It is the unit most people reach for to measure height, paper sizes and small objects in metric countries.
Both the Kilometre and the Centimetre are metric units, so converting between them is just a change of scale: one Kilometre equals 100,000 Centimetres, and the Kilometre is the larger unit.
