Convert centimeter/hour to kilometer/second
Please provide values below to convert centimeter/hour [cm/h] to kilometer/second [km/s], or Convert kilometer/second to centimeter/hour.
1 cm/h = 2.7778e-09 km/s. To convert centimeter/hour to kilometer/second, multiply the value by 2.7778e-09; to go the other way, divide by it (1 km/s = 359997120.023 cm/h). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cm/h = 2.7778e-09 km/s
- 1 km/s = 359997120.023 cm/h
- 10 cm/h = 2.7778e-08 km/s

Centimeter/hour
Centimeter per hour (cm/h) is a unit of speed that measures the distance in centimeters traveled or covered in one hour.
History/Origin
The centimeter per hour has been used primarily in scientific and industrial contexts to measure slow rates of movement or growth, especially in fields like biology and material science. Its usage became more standardized with the adoption of the metric system in the 19th century.
Current Use
Today, cm/h is used in applications such as measuring the rate of biological growth, sedimentation, or the movement of fluids and materials in scientific research and engineering.
Kilometer/second
A kilometer per second (km/s) is a unit of speed representing the distance of one kilometer traveled in one second.
History/Origin
The kilometer per second has been used in scientific contexts, particularly in astronomy and physics, to measure high velocities such as the speed of celestial objects and spacecraft. Its usage became prominent with the development of precise measurement techniques in the 20th century.
Current Use
Today, km/s is primarily used in astronomy, astrophysics, and space science to describe the velocities of stars, galaxies, and spacecraft. It is also used in scientific research involving high-speed phenomena.
Frequently Asked Questions
