Centimeters (cm) to Kilometers (km) Converter

How many centimeters (cm) are in 1 kilometer (km)? What is the formula for how to convert centimeters to kilometers (cm to km)?

1 centimeter (cm) = 0.00001 kilometer (km)
So we can say that there is 0.00001 kilometer in 1 centimeter.
This means that the multiplication conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 0.00001.

Inversely (or reciprocally),

1 kilometer (km) = 100,000 centimeters (cm)
So we can say that there are 100,000 centimeters in 1 kilometer.
This means that the division conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 100,000.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in centimeters to an equivalent quantity of length expressed in kilometers (cm to km). Both formulas will yield the same result. The formulas are:

km = cm × 0.00001    → This is the formula based on the multiplication conversion factor.

and

km = cm ÷ 100,000    → This is the formula based on the division conversion factor.

For example, if you have a length of 200000 centimeters that you want to convert to kilometers, you would use either of the two formulas as follows:

km = 200000 cm × 0.00001 = 2 km

km = 200000 cm ÷ 100,000 = 2 km

So, the result is the same using either formula, which is 2 kilometers.

Centimeters to kilometers (cm to km) conversion chart

To save you time and effort spent on having to perform manual calculations or look up conversion formulas every time a conversion from centimeters to kilometers is needed, here is a centimeters-to-kilometers conversion chart for your quick and easy reference. This conversion chart (or conversion table) shows common measurement values of length in centimeters and their equivalent measurement values in kilometers.

Conversion of 1 centimeter (cm) to other units of length

Here is a reference list providing a conversion of 1 centimeter (cm) to its equivalent values in various units of length, both metric and imperial:

What is a centimeter (cm)?

Definition of centimeter: A centimeter is a unit of length in the International System of Units (SI), commonly known as the metric system. It is equal to one hundredth of a meter (10^-2 m). It is often used for everyday measurements involving shorter distances than meters, such as human height.

The abbreviation for centimeter is cm. The single Unicode character ㎝ (U+339D) represents the 2-character Latin abbreviation for centimeter. The Windows Alt code for this character ㎝ is Alt + 13213.

What is a kilometer (km)?

Definition of kilometer: A kilometer is a unit of length in the International System of Units (SI), commonly known as the metric system, equal to one thousand meters (10^3 m). It is commonly used for longer distances, such as races, road distances and geographical features.

The abbreviation for kilometer is km. The single Unicode character ㎞ (U+339E) represents the 2-character Latin abbreviation for kilometer. The Windows Alt code for this character ㎞ is Alt + 13214.
