About These Units
Knot (kn)
A knot (kn or kt) equals one nautical mile per hour, approximately 1.151 mph or 1.852 km/h. Knots are the standard speed unit for ships, aircraft, and wind in maritime and aviation worldwide. Origin: sailors counted knots on a rope trailing behind the ship.
Foot per Second (ft/s)
Feet per second (ft/s or fps) measures speed in ballistics, projectile motion, and some US engineering applications. One ft/s equals 0.682 mph or 1.097 km/h. Bullet velocities range from 800-4,000 ft/s. Used for wind tunnel testing and fluid mechanics.
