What are knots and kilometers per hour?
A knot is one nautical mile per hour (1.852 km/h), used in aviation and shipping. Kilometers per hour is the standard metric unit for vehicle speed in most countries. For reference: a brisk walk is about 5 km/h (3 mph), and highway speed is around 100 km/h (62 mph).
How to convert knots to kilometers per hour
1 kn = 1.852 km/h. To convert, multiply the number of knots by 1.852. For example, 5 kn = 9.25998 km/h, and 20 kn = 37.0399 km/h. To go the other way, multiply kilometers per hour by 0.539958 (since 1 km/h = 0.539958 kn).
