About Yards per Second
A yard per second (yd/s) = exactly 0.9144 m/s - brisk jog speed, natural for American and British sports. American football wide receivers at full sprint: 10-11 yd/s; defensive backs 9-10 yd/s. Ten-pin bowling ball rolls the 20 yd lane in 2-3 s ≈ 7-9 yd/s. A sprinting cricket fielder covers the 22 yd pitch in ~3 s ≈ 7 yd/s. Racing greyhound: ~20 yd/s. 1 yd/s = 0.9144 m/s = 2.04545 mph.
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.
