Conversion Formula
v_orb = in/s × 3.315926893e-6
About Inches per Second
An inch per second (in/s) = exactly 0.0254 m/s = 25.4 mm/s. Professional reel-to-reel audio tape runs at 15 or 30 IPS; consumer tape decks at 1⅞ IPS; VHS at ~1.3 IPS. High-speed CNC axes rapid at 800-1,200 in/min ≈ 13-20 in/s. Pneumatic cylinder speeds and robotic end-effector approach speeds in US assembly plants are programmed in in/s. 1 in/s = 0.0254 m/s = 5 ft/min.
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.
