About These Units

Kilometers and Centimeters are linked by one constant: 100,000. Multiply your Kilometers figure by it and you have the answer in Centimeters — for example 10 Kilometers becomes 1,000,000 Centimeters. The calculator above handles decimals and large numbers alike; the reference table lists the values people look up most.

Kilometers and Centimeters measure the same physical quantity but belong to different scales, so moving a figure from Kilometers into Centimeters — or back again — is a routine step whenever specifications, prices, or measurements cross between the two systems.

About Kilometers

The kilometer (km) is 1,000 meters and the standard unit for road distances and geography in most of the world.

History

Introduced with the metric system in revolutionary France, it became the global standard for long-distance measurement.

About Centimeters

The centimeter (cm) is 1/100 of a meter, making it the natural unit for measuring small everyday objects.

History

Part of the original metric system introduced in 1795 in France.
