Convert kilometer/second to Mach (SI standard)

Please provide values below to convert kilometer/second [km/s] to Mach (SI standard) [M (SI)], or Convert Mach (SI standard) to kilometer/second.

1 km/s = 3.38753387534 M (SI). To convert kilometer/second to Mach (SI standard), multiply the value by 3.38753387534; to go the other way, divide by it (1 M (SI) = 0.2952 km/s). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.


Mach (Si Standard)

The Mach number is a dimensionless unit representing the ratio of an object's speed to the speed of sound in the surrounding medium.

History/Origin

Named after the Austrian physicist Ernst Mach, the Mach number was introduced in the early 20th century to describe supersonic and hypersonic speeds, initially used in aerodynamics and fluid dynamics research.

Current Use

The Mach number is widely used in aeronautics and astronautics to specify aircraft and spacecraft speeds relative to the local speed of sound, especially in high-speed flight regimes.
