About this tool
Convert centimeters to kilometers instantly. Free, bidirectional, and fully in-browser.
1 centimeter equals 1e-5 kilometers — enter any centimeter value to convert it to kilometers instantly. This Centimeter to Kilometer converter is a client-side tool: it applies a single multiplication (km = cm × 1e-5) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert kilometers back to centimeters. A reference table lists common centimeter values already converted, and nothing you enter is sent to a server.
Open Centimeter to Kilometer Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Centimeter field.
Read the equivalent in kilometers in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert kilometers to centimeters.
The result updates as you type, and the swap button flips the conversion to kilometer → centimeter without reloading.
The conversion uses the precise factor (km = cm × 1e-5), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One centimeter is 1e-5 kilometers. Multiply the centimeter value by 1e-5 to convert. For example, 10 cm = 0.0001 km.
km = cm × 1e-5. This tool applies it automatically and shows a worked example: 10 cm = 0.0001 km.
Yes. Press the swap button, or type into the kilometer field, and the tool converts kilometers to centimeters using the inverse of the same relationship.
It uses the standard distance and length definition (km = cm × 1e-5), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
