Formula
km/h = kn × 1.852
Multiply any value in knots by 1.852 to obtain the value in kilometres per hour.
Worked example
Convert 20 kn to km/h.
- 01Start with 20 kn.
- 02Multiply by the conversion factor: 20 × 1.852 = 37.04 km/h.
Result20 kn = 37.04 km/h

FAQ
What is the conversion factor from kn to km/h?
1 kn equals 1.852 km/h. To convert, multiply the value in knots by 1.852.
How do I convert 1 kn to km/h?
1 kn = 1.852 km/h. For any value, multiply by 1.852.
How do I convert km/h back to kn?
Divide by the same factor — or equivalently, multiply by 0.5399568. So 1 km/h = 0.539957 kn.
When would I need to convert knot to kilometre per hour?
Velocity conversions are needed for fluid flow analysis (line velocity targets, erosional limits), gas-stream calculations, and equipment specs that mix m/s, ft/s and engineering speed units.
Is the conversion exact?
Yes. Both kn and km/h are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
