Knot

The knot equals one nautical mile per hour — 1.852 km/h. It is the international standard in marine navigation and aviation. Commercial airliners cruise at 450–500 knots. Sailboats in light breeze: 2–6 knots.

Centimeter per Second

cm/s

Centimetres per second (cm/s) is used for slow-moving phenomena — ocean currents, earthworms, biological cell motion. Typical ocean surface currents: 10–100 cm/s. Continental drift: about 2–10 cm/year (converted: very slow cm/s).

Real-world: Gulf Stream: 100–200 cm/s. Amoeba: 1 mm/s = 0.1 cm/s. Sediment settling: 0.01–1 cm/s.

Tips & common mistakes

Quick tips

1 knot = 1.852 km/h = 1.151 mph.
Knots cannot be abbreviated "kt" in sailing — standard is "kn".
A 40-knot wind is storm-force — 74 km/h.

Avoid these

Reading 40 knots as 40 km/h in weather — 74 km/h is much stronger.
Using "knots per hour" — already a rate; it's just "knots".
Treating knot as a distance unit — it's always a speed.
