## How to Convert Kilometers to Centimeters

To convert a measurement in kilometers to a measurement in centimeters, multiply 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:

centimeters = kilometers × 100,000

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

For example, here's how to convert 5 kilometers to centimeters using the formula above.
centimeters = (5 km × 100,000) = 500,000 cm

### How Many Centimeters Are in a Kilometer?

There are 100,000 centimeters in a kilometer, which is why we use this value in the formula above.

1 km = 100,000 cm

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

## What Is a Kilometer?

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in 1/299,792,458 of a second.[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 103. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.

## 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.
