Formula and methodology
Formula: 1 kn = 1852 m/h; mph = knots×1.150779448; km/h = knots×1.852; m/s = knots×0.5144444444.
A knot is one nautical mile per hour, and the international nautical mile is exactly 1,852 metres. The converter shows both maritime and land-speed units.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Speed in knots — kn; minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Speed in knots | 20 |
20 kn = 23.0156 mph = 37.04 km/h = 10.2889 m/s.
Assumptions and limits
- The knot uses the international nautical mile, not a historical local nautical mile.
- The input is a speed and may be signed for direction in an algebraic calculation.
- No wind, current, ground-speed, or airspeed interpretation is added.
