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 Miles per Hour
A mile per hour (mph) = exactly 0.44704 m/s - the primary road speed unit in the US, UK, and a few other countries. US interstate limits 65-85 mph; UK motorway 70 mph. Walking ~3-4 mph; club cycling 20-25 mph. MLB elite fastball 100 mph (44.7 m/s). Saffir-Simpson Category 5 hurricane ≥157 mph. Boeing 737 MAX cruises at ~521 mph (Mach 0.79). 1 mph = 0.44704 m/s = 1.60934 km/h = 0.86898 kn.
