About these units
Mile/Second (mi/s)
A mile per second is an extraordinarily fast speed—3,600 mph—far beyond any ground vehicle. This unit appears primarily in discussions of orbital mechanics, rocket propulsion, and reentry dynamics. Projectiles in theoretical physics or high-energy impact modeling may also be described in miles per second. The unit's infrequent use reflects its specialized nature, but its dramatic magnitude makes it compelling for illustrating the extremes of velocity attainable in space travel and astrophysics.
Millimeter/Second (mm/s)
A millimeter per second is a useful speed in robotics, precision machining, biomechanics, and controlled engineering systems. Robotic arms performing delicate manipulation, small servo motors, and scanning instruments often operate in the mm/s speed range. In seismology, mm/s measures the vibration velocities of the ground during micro tremors, making it essential in structural engineering and earthquake monitoring. It reflects the world of fine-scale, controlled motion—beyond what the human eye typically detects.
