About these units
Yard/Hour (yd/h)
A yard per hour is extremely slow and used only in rare cases where long-term monitoring of tiny movements is necessary—such as soil settlement in construction sites, creeping machinery, or long-term structural drift. Because the yard is an everyday imperial unit, yd/h sometimes appears in engineering logs or legacy datasets, though it is largely replaced by ft/h or mm/h in modern practice. Its use reflects the persistence of imperial measurements in certain specialized contexts.
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.
