About these units
Kilometer/Second (km/s)
A kilometer per second represents a very high speed—1,000 meters every second—and is particularly important in astronomy, planetary science, and astrophysics. Orbital velocities around planets, escape velocities, solar winds, and the motion of stars relative to each other are commonly measured in km/s. This scale captures speeds far beyond terrestrial transportation. For example, Earth orbits the Sun at roughly 30 km/s, and meteoroids entering Earth's atmosphere may arrive at speeds between 11 and 72 km/s. km/s is a natural step up from m/s when describing the motion of celestial bodies.
Centimeter/Second (cm/s)
A centimeter per second is widely used in hydrology, biology, and physics to measure modest fluid flows, blood velocities, small organism movement, or lab-scale chemical transport. In medicine, cm/s is important in Doppler ultrasound, where blood flow speeds in arteries and veins are routinely measured. In physical sciences, cm/s appears in low-speed fluid mechanics experiments, sediment transport studies, and oceanographic microcurrent analysis. It offers a convenient, human-comprehensible scale for small but dynamic systems.
