centimeter per second to kilometer per hour
Convert centimeter per second (cm/s) to kilometer per hour (km/h). Use an editable speed converter, conversion formula, and reference table.
1 cm/s = 0.036 km/h
Conversion formula
One centimeter per second equals 0.036 kilometer per hour. Multiply your value in centimeter per second by this factor to get kilometer per hour. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 centimeter per second:5 × 0.036 = 0.18 km/h

About these measurements
Speed is distance traveled per unit of time.
The base reference used here is the meter per second. One centimeter per second is 0.01 base units; one kilometer per hour is 0.2777777778 base units.
Important distinctions
Mach is excluded because the speed of sound depends on medium and temperature.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert cm/s to km/h?
Multiply the quantity in cm/s by 0.036. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the kilometer per hour to centimeter per second converter.
