Converting Foot per Sec to Knot is a common speed conversion. One foot per sec (ft/s) equals 0.592484313 knot (kn). Feet per second are used in ballistics, engineering, and some US speed calculations.
This conversion is commonly needed for physics and engineering calculations, driving and speed limit compliance, running and fitness tracking. Knots are the standard speed unit in maritime and aviation worldwide.
To put foot per sec in perspective: the speed of sound (about 1,125 ft/s). In knot, common references include a cruise ship (about 20 kn).
Feet per second is commonly used in ballistics to describe projectile muzzle velocity, giving more intuitively sized numbers than meters per second for that range of speeds.
The term 'knot' originated from counting knots on a rope trailing behind a ship over a fixed time period.
