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.
Mile/Minute (mi/min)
A mile per minute corresponds to 60 miles per hour, making it a bridge between mph and high-speed conceptual measures. Aircraft climb rates, emergency vehicle response metrics, and theoretical speed comparisons sometimes use mi/min for rapid mental calculations. The unit is also used historically in railway performance, where achieving "a mile a minute" once symbolized extraordinary locomotive speed. Today it stands as both a technical unit and a romantic benchmark of transportation history.
