About this conversion

The centimeter (cm) is a unit of length in the metric (SI), commonly used for clothing and shoe sizes and human height and body measurements. The kilometer (km) belongs to the metric (SI) and is typically found in measurements related to road and highway distances and geographic measurements. By definition, one centimeter is one hundredth of a meter (0.01 m). One kilometer is one thousand meters. The conversion factor between these two units is 0.00001: multiplying any value in cm by this number gives the equivalent in km. For example, 10 cm equals 0.0001 km. Going the other direction, 1 km equals 100000 cm. The centimeter has been part of the metric system since its adoption in France in the late 18th century. Adopted alongside the metric system, the kilometer became the standard unit for land distance in most countries by the 20th century.
