How to Convert Centimeters to Kilometers
To convert a centimeter measurement to a kilometer measurement, divide the length by the conversion ratio. One kilometer is equal to 100,000 centimeters, so use this simple formula to convert:
The length in kilometers is equal to the centimeters divided by 100,000.
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.
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.
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.
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.
