## How to Convert Centimeters to Kilometers

To convert a measurement in centimeters to a measurement in kilometers, divide the length by the following conversion ratio: 100,000 centimeters/kilometer.

Since one kilometer is equal to 100,000 centimeters, you can use this simple formula to convert:

The length in kilometers is equal to the length in centimeters divided by 100,000.

**For example,**here's how to convert 500,000 centimeters to kilometers using the formula above.

Our inch fraction calculator can add centimeters and kilometers together, and it also automatically converts the results to US customary, imperial, and SI metric values.

Centimeters and kilometers are both units used to measure length. Keep reading to learn more about each unit of measure.

## What is a Centimeter?

One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in ^{1}/_{299,792,458} of a second.
One centimeter is equal to 0.393701 inches.

The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for hundredths, or 10^{-2}. Centimeters can be abbreviated as *cm*; for example, 1 centimeter can be written as 1 cm.

Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard number 2 pencil is just about 1 cm thick.

## What is a Kilometer?

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.^{[1]} One kilometer is equal to 0.621371 miles.

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for thousands, or 10^{3}. Kilometers can be abbreviated as *km*; for example, 1 kilometer can be written as 1 km.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or a combination of both values, so make sure you get the correct type for your needs.
