Conversion Formula
mm/s = v_esc × 11186000
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.
About Millimetres per Second
A millimetre per second (mm/s) is 10⁻³ m/s - the speed of slow industrial mechanisms and recognisable biological motion. FDM 3D printers move at 40-120 mm/s for perimeters and 150-300 mm/s for infill. Garden snails travel 0.5-1.5 mm/s; earthworms 3-5 mm/s. CNC finishing operations run 1-several hundred mm/s. Hydraulic precision slides work at mm/s for surface preparation. Ultrasound particle velocities in soft tissue are also in this range. 1 mm/s = 10⁻³ m/s.
