About these units
Knot (kt)
A knot is equal to one nautical mile per hour, or 1.852 km/h, and is the standard unit of speed in aviation and maritime navigation. Knots are intimately linked to navigation because nautical miles represent distances along Earth's spherical surface. A ship or aircraft traveling at 1 knot moves over one minute of arc of latitude in one hour—reflecting its origins in astronomical navigation. Using knots allows mariners and pilots to integrate seamlessly with charts, headings, coordinate systems, and wind speed conventions. The unit symbolizes centuries of seafaring tradition and remains indispensable for global navigation.
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.
