How to Convert Centimeters to Kilometers

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

Convert centimeters to kilometers with this simple formula:

kilometers = centimeters × 1.0E-5

Converting a centimeter length measurement to a kilometer measurement involves multiplying the length by the conversion ratio to find the result. One centimeter is equal to 1.0E-5 kilometers, so to convert simply multiply by 1.0E-5.

For example, here's how to convert 5 centimeters to kilometers using the formula above.
5 cm = (5 × 1.0E-5) = 5.0E-5 km

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.

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.
