About Metres per Minute
A metre per minute (m/min) equals exactly 1/60 m/s ≈ 0.016667 m/s and is widely used in manufacturing, printing, and industrial processes as a natural metric extension. CNC router cutting feeds in metric workshops are specified in m/min: wood at 3-10 m/min, aluminium at 1-4 m/min. High-speed printing press web speeds range from a few m/min on proof presses to 600-1,200 m/min on modern flexographic machines; inkjet web printers run at 50-200 m/min. Treadmill running speeds are resolved to m/min in training-intensity calculations: walking 80-100 m/min, jogging 150-180 m/min, running 240-300 m/min. Elite 100 m freestyle swimmers complete their length in about 47 seconds - approximately 127 m/min. Wind turbine blade hub speeds of large utility turbines reach 60-100 m/min at rotor hub radius, rising to 400+ m/min at the blade tip. Paper machine wire speeds in modern fourdrinier mills run at 60-1,200 m/min depending on grade. 1 m/min = 1/60 m/s ≈ 0.06 km/h = 3.281 ft/min.
About Mach 20
Mach 20 ≈ 6,805.8 m/s (24,501 km/h) at ISA sea level - the peak heating regime of ballistic re-entry. Shock layer temperature exceeds 10,000 K; plasma sheath causes radio blackout. Space Shuttle decelerated through Mach 20 at ~75-80 km altitude; Apollo CM hit the atmosphere at ~Mach 36; ICBM warheads re-enter at Mach 18-24. DARPA HTV-2 reached Mach 20 in 2011. 1 Mach 20 = 6,805.8 m/s.
