Convert Knots to Kilometres per hour
1 knot is 1.852 km/h. One knot is exactly 1.852 kilometres per hour.
One knot is 1.852 kilometres per hour. To convert knots to kilometres per hour, multiply by 1.852; to go the other way, divide by 1.852 or multiply by 0.5399568. The factor is exact rather than rounded: it follows from NIST Special Publication 811. One nautical mile per hour — exactly 1,852 metres per hour.

What are knots and kilometres per hour?
- Knot (kn)
- One nautical mile per hour — exactly 1,852 metres per hour. Used at sea and in the air because a nautical mile is one minute of latitude, which makes navigation arithmetic simple.
- Kilometre per hour (km/h)
- Exactly one kilometre divided by 3,600 seconds. The road speed unit almost everywhere outside the United States and the United Kingdom.
