Enter the length in kilometers below to get the value converted to centimeters.
How to Convert Kilometers to Centimeters
To convert a kilometer measurement to a centimeter measurement, multiply the length by the conversion ratio. One kilometer is equal to 100,000 centimeters, so use this simple formula to convert:
The length in centimeters is equal to the kilometers multiplied by 100,000.
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 and centimeters are both units used to measure length. Keep reading to learn more about each unit of measure.
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 1cm 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.
If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
