- 1 kn = 1.852 km/h
- 1 × 1.852 = 1.852 km/h
How to convert knots to kilometers per hour
1 kn = 1.852 km/h, so multiply by 1.852 to go from knots to kilometers per hour. Going the other way, 1 km/h = 0.539956803456 kn.
km/h = kn × 1.852 kn = km/h × 0.539956803456
Worked example:
1 kn = 1.852 km/h 5 × 1.852 = 9.26 km/h
