About these units
Millimeter/Minute (mm/min)
A millimeter per minute is a slow mechanical speed often encountered in CNC machining, automated laboratory equipment, and controlled industrial processes. In medicine, infusion pumps, surgical robotics, and controlled incisions may specify movement in mm/min to maintain safety and precision. By using millimeters instead of centimeters or meters, the unit ensures fine control in delicate operations where even small deviations matter.
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.
