Kilometer/second
The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.
Mile/second
The mile per second (mi/s) is a unit of speed representing the number of miles an object travels in one second. This unit is extremely fast and is generally used in contexts such as space exploration or when describing the speed of meteors or other fast-moving astronomical objects.
