About Miles per Second
A mile per second (mi/s) = exactly 1,609.344 m/s - above the fastest air-breathing aircraft. NASA X-43A scramjet: 2.9 km/s ≈ 1.8 mi/s (Mach 9.6). Earth's orbital speed around the Sun: ~18.5 mi/s (29.8 km/s). Light travels ~186,282 mi/s in vacuum - the classic imperial figure still used in popular astronomy. Tunguska impactor entered Earth's atmosphere at ~9-11 mi/s. 1 mi/s = 3,600 mph = 3,128.3 kn.
About Feet per Minute
A foot per minute (ft/min) = 5.08 × 10⁻³ m/s - the US standard for elevator speed, HVAC duct velocity, and conveyor speed. Residential lifts: 100-200 ft/min; commercial 200-400 ft/min; skyscraper express lifts 1,000-3,000 ft/min (Burj Khalifa 2,953 ft/min). HVAC low-velocity ductwork: 500-1,000 ft/min; medium-velocity 1,000-2,200 ft/min. Paper machine Fourdrinier wires: 200-6,000 ft/min. 1 ft/min = 0.00508 m/s.
