Convert your speed from km/h to nautical knots. Useful when your GPS shows km/h but you want to know your speed in the standard marine unit.
| Kilometers per hour (km/h) | Knots (kn) |
|---|---|
| 5 | 2.7 |
| 10 | 5.4 |
| 15 | 8.1 |
| 20 | 10.8 |
| 25 | 13.5 |
| 30 | 16.2 |

| 100 | 54 |
To convert km/h to knots, divide by 1.852. If your GPS shows a top speed of 50 km/h, that's 27 knots — a solid speed for kitesurfing or windsurfing.
Knots are the international standard for marine speed because one knot equals one nautical mile per hour, and nautical miles map directly to degrees of latitude, making navigation calculations straightforward. In watersports, knowing your speed in knots helps you compare with other riders and understand weather forecasts.
