Conversion Formula
v_esc = ft/min × 4.541391024e-7
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.
About Earth Escape Velocity
Earth's escape velocity = 11,186 m/s at the surface - v_esc = √(2GM/r). A spacecraft launched at this speed (any direction) escapes on a parabolic trajectory; less gives an elliptical orbit. Apollo's trans-lunar injection exceeded this to reach the Moon. Voyager, Pioneer, and New Horizons all exceeded 11.2 km/s at launch. Moon escape velocity 2.38 km/s; Mars 5.03 km/s; Jupiter 59.5 km/s. 1 Earth v_esc ≈ 11,186 m/s = 40,270 km/h.
