Convert Inches per Second (in/s) to Earth Escape Velocity (v_esc) instantly and accurately.
Conversion Formula
v_esc = in/s × 2.270695512e-6
About Inches per Second
An inch per second (in/s) = exactly 0.0254 m/s = 25.4 mm/s. Professional reel-to-reel audio tape runs at 15 or 30 IPS; consumer tape decks at 1⅞ IPS; VHS at ~1.3 IPS. High-speed CNC axes rapid at 800-1,200 in/min ≈ 13-20 in/s. Pneumatic cylinder speeds and robotic end-effector approach speeds in US assembly plants are programmed in in/s. 1 in/s = 0.0254 m/s = 5 ft/min.
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.
