How to convert knots to feet per second

Multiply the value in kn by 1.6878098571: the result is in ft/s.

ft/s = kn × 1.6878098571The other way round, 1 ft/s = 0.592483801296 kn.

Where these two units are used

The knot is one nautical mile per hour, exactly 1.852 kilometers per hour since 1929, and it is tied to geography: a nautical mile is one minute of latitude. The foot per second serves American ballistics, where muzzle velocity is always quoted this way, and free-fall calculations. One cockpit uses both at right angles: horizontal speed reads in knots, vertical speed in feet per minute, and a knot is 1.69 ft/s.
