Knots (kn) to Feet per second (ft/s) Conversion
Knots
The knot is a unit of speed equal to exactly one nautical mile per hour (1.852 km/h), the standard unit for maritime and aerial navigation worldwide. Its name derives from the historical practice of measuring ship speed using a knotted rope thrown overboard. Because the nautical mile is tied to the Earth's geometry (one arcminute of latitude), a ship at 1 knot crosses one arcminute of latitude per hour.
Feet per second
Feet per second (ft/s) is a unit of speed in the US customary and imperial systems equal to approximately 0.3048 m/s or 1.09728 km/h. It is commonly used in ballistics to express projectile velocities, in structural engineering for wind speed calculations, and in sports science. The speed of sound at sea level is approximately 1,125 ft/s (343 m/s), a reference used in firearms and aeronautics.
