Kilometer/second
The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.
Mach (SI standard)
The Mach number (Mach) is a dimensionless unit used to express the speed of an object relative to the speed of sound in the surrounding medium. A Mach number of 1 indicates the speed of sound, with higher numbers representing supersonic or even hypersonic speeds. This unit is critical in aerodynamics and aerospace engineering.
