Conversion Formula
v_orb = in/min × 5.526544822e-8
About Inches per Minute
An inch per minute (in/min) ≈ 0.4233 mm/s - the standard North American machining feed unit for slow precision cuts. CNC milling in titanium or nickel superalloys: HSS roughing 2-8 in/min; carbide finishing 15-40 in/min. Thread-tapping feeds are calculated in in/min from pitch × RPM. Hydraulic press platen closure for rubber moulding and laminate pressing: 0.05-2 in/min. 1 in/min = 0.0254 m/min ≈ 4.233 × 10⁻⁴ 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.
