About Metres per Second
The metre per second (m/s) is the SI unit of speed. Brisk walking ~1.4 m/s; Usain Bolt's peak sprint ~12.4 m/s; speed of sound in air at 20°C 343.2 m/s; in water 1,481 m/s. Rifle muzzle velocities 370-1,200 m/s. Speed of light = exactly 299,792,458 m/s (the defined constant from which the metre is derived since 1983). 1 m/s = 3.6 km/h = 2.23694 mph = 1.94384 kn.
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.
