About Millimetres per Second
A millimetre per second (mm/s) is 10⁻³ m/s - the speed of slow industrial mechanisms and recognisable biological motion. FDM 3D printers move at 40-120 mm/s for perimeters and 150-300 mm/s for infill. Garden snails travel 0.5-1.5 mm/s; earthworms 3-5 mm/s. CNC finishing operations run 1-several hundred mm/s. Hydraulic precision slides work at mm/s for surface preparation. Ultrasound particle velocities in soft tissue are also in this range. 1 mm/s = 10⁻³ m/s.
About Orbital Speed (ISS)
The ISS orbits at ~408 km altitude at ≈7,660 m/s (27,576 km/h) - the practical LEO benchmark. At this speed it completes one orbit in 92.68 min (15.5 orbits per day), giving astronauts 16 sunrises and sunsets every 24 hours. Delta-v to reach LEO from Earth's surface is ~9,400 m/s (with gravity and drag losses). GEO at 35,786 km requires only ~3,075 m/s per Kepler's third law. 1 ISS speed ≈ 7,660 m/s.
