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 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.
