Formula
One international knot is one nautical mile per hour, and that nautical mile is 1.852 kilometers:
km/h = knots × 1.852
A statute mile is shorter than a nautical mile, so the miles-per-hour page uses 1.609344 instead.
Assumptions
- The value can be zero and cannot be negative.
- The result is shown with up to six decimal places.
Worked example
1 knot equals 1.852 kilometers per hour.
Input definitions
- Knots
- Nautical miles per hour.
Limitations
Boat or aircraft instruments can read indicated speed rather than speed over the ground. This page converts the number you type.
