This page opens the speed converter preset to knots → kilometers per hour. One knot is one nautical mile per hour, and the nautical mile is defined as exactly 1,852 meters, so 1 knot = 1.852 km/h exactly. The nautical mile matches one minute of latitude, which is why ships and aircraft still use it.
Anchors from the water and sky: a 10-knot breeze is 18.5 km/h, 20 knots of sailing wind is 37 km/h, a 30-knot gale is 55.6 km/h, and a ferry cruising at 40 knots does 74.1 km/h. Airliners approach the runway at roughly 130–140 knots, about 240–260 km/h.
Sailors reading forecasts, pilots and flight-sim fans, kitesurfers checking wind apps and anyone following marine weather will use this constantly. Type knots to get km/h live; the table beneath the result lists typical wind and vessel speeds.
