About knots and kilometers per hour
Knot (kn)
A knot is one nautical mile per hour, about 0.514444 meters per second. It is used for ship, aircraft and wind speeds.
Kilometer per hour (km/h)
A kilometer per hour is 1/3.6 of a meter per second. It is used for road speed limits and vehicle speeds in most countries.
Both are units of speed; the base unit used internally is m/s.
Notes
- The knot is one international nautical mile per hour (1852/3600 m/s ≈ 0.514444 m/s).
- Negative values are accepted to represent velocity along a signed axis.
kn to km/h FAQs
How do I convert knots to kilometers per hour?
Multiply the number of knots by 1.852 to get kilometers per hour. For example, 25 kn × 1.852 = 46.3 km/h.
How many kilometers per hour are in one knot?
1 kn = 1.852 km/h and 1 km/h = 0.5399568035 kn. To go the other way, use the kilometers per hour to knots converter.
