How to Convert Kilometers to Centimeters

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

Convert kilometers to centimeters with this simple formula:

centimeters = kilometers × 100,000

Converting a kilometer length measurement to a centimeter measurement involves multiplying the length by the conversion ratio to find the result. One kilometer is equal to 100,000 centimeters, so to convert simply multiply 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

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.
