About Kilometres per Minute

A kilometre per minute (km/min) = 50/3 m/s ≈ 16.667 m/s. F1 cars at Monza average ~4.33 km/min in qualifying. High-speed trains (TGV, ICE) cruise at 2.5-3.5 km/min. Subsonic military jet trainers fly at 3-7 km/min; combat aircraft cruise at 7-10 km/min. Dead-reckoning navigation: elapsed minutes × km/min = distance. 1 km/min = 60 km/h = 37.28 mph.

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.
