Convert kilometer/second to millimeter/second

Please provide values below to convert kilometer/second [km/s] to millimeter/second [mm/s], or Convert millimeter/second to kilometer/second.




How to Convert Kilometer/second to Millimeter/second

1 km/s = 1000000 mm/s

Example: convert 15 km/s to mm/s:
15 km/s = 15 × 1000000 mm/s = 15000000 mm/s

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.


Millimeter/second

Millimeter per second (mm/s) is a unit of speed representing the distance of one millimeter traveled in one second.

History/Origin

The millimeter per second has been used in scientific and engineering contexts to measure small-scale velocities, especially in fields like fluid dynamics and material science, as a standard unit derived from the metric system.

Current Use

Today, mm/s is commonly used in scientific research, engineering, and technical applications to quantify low velocities, such as in microfluidics, biomechanics, and precision manufacturing.
