The Beaufort scale is an empirical wind-force scale from 0 (calm) to 12 (hurricane). Created by Francis Beaufort in 1805, it correlates wind force with observed effects on sea or land. Force 8 (34โ40 knots) is a gale; force 12 is above 64 knots.
Real-world: Force 5 (fresh breeze): 17โ21 knots, white-caps form. Force 8 (gale): 34โ40 knots. Force 12: 64+ knots.

Real-world: Gulf Stream: 100โ200 cm/s. Amoeba: 1 mm/s = 0.1 cm/s. Sediment settling: 0.01โ1 cm/s.
