About Micrometres per Second
A micrometre per second (µm/s) is 10⁻⁶ m/s - the speed of cell motility, bacteria, and precision machining feeds. E. coli swims at 20-30 µm/s; the fastest bacteria (Thiovulum majus) reach 600 µm/s. Neutrophils chasing a chemoattractant move at 10-20 µm/s. Microfluidic lab-on-chip analytical channels flow at 1-1,000 µm/s. Diamond-turning lathe in-feeds for optical surfaces are 1-100 µm/s. Fast glacier centrelines move ~1-10 µm/s (~100 m/year). 1 µm/s = 10⁻⁶ m/s.
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.
