Knots to km/h – convert knots to kilometres per hour
Convert knots to km/h for boats, ships, aviation and weather reports. This page opens the main speed converter with knots → km/h pre-selected so you can type any nautical speed and see the result in kilometres per hour.
Open the interactive knots → km/h converter:
Use main converter (knots → km/h) or switch to km/h → knotsThe homepage also lets you convert knots to mph and m/s. Try the Tool Hub stopwatch or timer for boat tests or flying circuits.
Quick reference: knots to km/h
By definition, 1 knot ≈ 1.852 km/h, so: km/h = knots × 1.852.
| Knots | km/h (approx.) |
|---|---|
| 5 kn | 9.3 km/h |
| 10 kn | 18.5 km/h |
| 15 kn | 27.8 km/h |
| 20 kn | 37.0 km/h |
| 30 kn | 55.6 km/h |
| 40 kn | 74.1 km/h |
How to convert knots to kilometres per hour
Use:
km/h = knots × 1.852
Examples:
- 8 kn × 1.852 ≈ 14.8 km/h
- 25 kn × 1.852 ≈ 46.3 km/h
- 50 kn × 1.852 ≈ 92.6 km/h
Where knots → km/h is used
- Converting boat and ship speeds into familiar land-speed units.
- Understanding aviation reports that quote airspeed in knots.
- Comparing wind speeds given in knots with forecasts in km/h.
- Relating nautical speeds to driving times and distances on land.

In the converter, knots are internally converted via metres per second, keeping results consistent when you switch between mph, km/h and knots.
