Knots to kilometers per hour

1 knot in kilometers per hour
1 kn = 1.852 km/h
km/h = kn × 1.852

To convert knots to kilometers per hour, multiply by 1.852. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is km/h = kn × 1.852. Both units measure speed, so the conversion is a fixed factor that never changes.

Common questions

How many kilometers per hour are in one knot?
One knot equals 1.852 kilometers per hour. km/h = kn × 1.852.
How do you convert knots to kilometers per hour?
Use km/h = kn × 1.852. So 10 kn is 18.52 km/h.
How many knots are in one kilometer per hour?
One kilometer per hour equals 0.53996 knots, which is the reverse of the conversion above.
