Kilometers Per Hour to Knots Converter
How to convert kilometers per hour to knots
knots = kilometers per hour ÷ 1.852
To convert kilometers per hour to knots, divide the number of kilometers per hour by 1.852.
1 km/h = 0.539956803 kn
Examples
- A common highway speed limit: 100 km/h ÷ 1.852 = 53.9956803 kn
- 50 km/h ÷ 1.852 = 26.9978402 kn
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.
