About the Units

Centimeter (cm)

A centimeter is a unit of length in the metric system, equal to one hundredth of a meter (0.01 m). Centimeters are commonly used for measuring small lengths, body height, screen sizes, and everyday objects. The centimeter is widely used in science, medicine, and daily life worldwide.

Kilometer (km)

A kilometer is a unit of length in the metric system, equal to 1,000 meters or 100,000 centimeters. It is the standard unit for measuring distances between geographical locations in most countries worldwide. Kilometers are used on road signs, maps, and GPS systems across Europe, Asia, South America, and Africa.

Frequently Asked Questions

How many km is 1 cm?

1 centimeter is equal to 0.00001 kilometers (1/100,000 of a kilometer).

How do I convert cm to km?
