# Kilometers to Centimeters Conversion

Enter the length in kilometers below to get the value converted to centimeters.

Results in Centimeters: 1 km = 100,000 cm
1 km = 1,000 m

## How to Convert Kilometers to Centimeters

To convert a kilometer measurement to a centimeter measurement, multiply the length by the conversion ratio.

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 kilometers multiplied by 100,000.

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

## Kilometers

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.

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 103. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.

## Centimeters

One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

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 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 pencil is just about 1 cm thick.

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 combination with both values, so make sure you get the correct type for your needs.
