Kilometers per Hour to Knots (km/h to kn) Converter
1 kilometer per hour (km/h) = 0.539957 knots (kn). To convert kilometers per hour to knots, multiply by 0.539957: 100 km/h × 0.539957 = 53.9957 kn. Also searched as kph to knot, kmph to knot, kilometres per hour to knots.
Quick facts
- 1 km/h = 0.539957 kn
- 1 kn = 1.852 km/h
- Formula: kn = km/h × 0.539957
- Quick estimate: multiply by about 0.54
How to convert kilometers per hour to knots
- Take the value in kilometers per hour.
- Multiply it by 0.539957 (the number of knots in one kilometer per hour).
- Round the result to the precision you need.
Worked example (motorway driving): 100 km/h × 0.539957 = 53.9957 kn.
To convert knots back to kilometers per hour, multiply by 1.852, or divide by 0.539957.
