About Knot and Meters per Second

The knot is one nautical mile per hour, exactly 1.852 km/h. Ships, aircraft, and weather charts use knots because the nautical mile maps onto latitude minutes. The meter per second is the SI derived unit of speed. Physics, wind reporting in many countries, and sprint analysis use it directly, and every other speed unit converts through it. One Knot equals 0.514444444 Meters per Second (1 knot = 0.514444444 mps). Knot is used in ship and boat speeds and in aircraft airspeed. Meters per Second is used in physics calculations.

Precision and Rounding:Most speed factors are exact because they derive from exact length and time definitions (1 mph = 1.609344 km/h precisely); Mach is the exception, since the speed of sound varies with temperature and altitude. The figure used here is 343 m/s, the sea-level value at 20 °C. One decimal place covers driving and running; aviation and ballistics carry more.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
