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 Kilometres per Second
A kilometre per second (km/s) = 1,000 m/s - the scale of orbital mechanics and hypervelocity. ISS orbital speed ≈ 7.66 km/s; Earth escape velocity 11.186 km/s. Voyager 1 travels ~17 km/s relative to the Sun. Meteoroids enter Earth's atmosphere at 11-72 km/s; solar wind 400-800 km/s. High-explosive detonation fronts propagate at 6.9-8.8 km/s. 1 km/s = 3,600 km/h = 2,236.9 mph.
