About Nautical Miles per Minute

A nautical mile per minute (nmi/min) = 1,852/60 m/s ≈ 30.867 m/s = 60 knots. At 1 nmi/min, elapsed time in minutes equals distance in nautical miles - dead-reckoning made trivial. Mach 1 at sea level ≈ 1.1 nmi/min; Concorde at Mach 2.02 flew ~3 nmi/min. ATC radar separation standards use nmi and minutes as native units, making nmi/min the implicit reference. 1 nmi/min = 1,852 km/h = 60 kn.

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.
