Knots to Kilometers per Hour (kn to km/h) Converter
1 knot (kn) = 1.852 kilometers per hour (km/h). To convert knots to kilometers per hour, multiply by 1.852: 20 kn × 1.852 = 37.04 km/h. Also searched as knots to kilometres per hour.
Quick facts
- 1 kn = 1.852 km/h
- 1 km/h = 0.539957 kn
- Formula: km/h = kn × 1.852
- Quick estimate: multiply by about 1.9
How to convert knots to kilometers per hour
- Take the value in knots.
- Multiply it by 1.852 (the number of kilometers per hour in one knot).
- Round the result to the precision you need.
Worked example (a ferry's cruising speed): 20 kn × 1.852 = 37.04 km/h.
To convert kilometers per hour back to knots, multiply by 0.539957, or divide by 1.852.
