Knots to Kilometers Per Hour Converter
How to convert knots to kilometers per hour
kilometers per hour = knots × 1.852
To convert knots to kilometers per hour, multiply the number of knots by 1.852.
1 kn = 1.852 km/h
Examples
- 10 kn × 1.852 = 18.52 km/h
- 30 kn × 1.852 = 55.56 km/h
Good to know
One knot is exactly 1.852 km/h, because a nautical mile is exactly 1,852 meters. Doubling the knots and subtracting 10% gives a close km/h estimate.
