Knots to Kilometers per hour
Type a value in kn and get km/h instantly: 1 kn = 1.852 km/h
1 kn = 1.852 km/h
⇄ Kilometer per hour → KnotThe conversion between knots (kn) and kilometers per hour (km/h) is fixed: 1 kn = 1.852 km/h and 1 km/h = 0.54 kn. To convert kn to km/h, multiply by 1.852; to go the other way, multiply by 0.54 (or divide by 1.852). For example, 10 kn = 18.52 km/h and 30 kn = 55.56 km/h.
Enter any value in the converter above; the result updates as you type. You will also find a ready-made table for common values, the formula, and a link to the reverse conversion (kilometers per hour to knots).
One knot is one nautical mile per hour: exactly 1.852 km/h. Wind, boat and aircraft speeds use knots; a hurricane starts at 64 kn ≈ 118.5 km/h on the Beaufort scale.
