Convert mile/second to kilometer/second

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

1 mi/s = 1.609344 km/s. To convert mile/second to kilometer/second, multiply the value by 1.609344; to go the other way, divide by it (1 km/s = 0.621371192237 mi/s). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

Mile/second

A mile per second (mi/s) is a unit of speed representing the distance of one mile traveled in one second.

History/Origin

The mile per second has been used primarily in scientific contexts, especially in astronomy and physics, to measure extremely high velocities such as those of celestial objects. Its usage has been limited due to the convenience of metric units in scientific measurement.

Current Use

Today, the mile per second is mainly used in scientific research, particularly in astrophysics and space science, to describe high-velocity phenomena like the speed of spacecraft, stars, or other celestial bodies.


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.
