Feet per second to Knots Converter

To convert a measurement in feet per second to knots, multiply the value by 0.592483801296. The conversion factor comes from the relationship between both units and the meter per second.

For example, to convert 5 ft/s to knots: 5 × 0.592483801296 = 2.962419 kn.

The foot per second is an imperial unit of speed equal to one foot traveled in one second, or exactly 0.3048 meters per second. Ft/s is common in US engineering and ballistics, where distances are measured in feet. Muzzle velocities, fluid flow, and free-fall speeds are frequently expressed this way.

Common uses of feet per second include: Ballistics and muzzle velocity; US engineering and fluid flow; Free-fall and projectile physics; Conveyor and belt speeds.

A knot is a unit of speed equal to one nautical mile per hour, or exactly 1.852 km/h (about 0.514 m/s). The knot dates from the age of sail, when speed was measured by counting knots on a rope paid out behind a ship over a timed interval. It remains standard in marine and air navigation.

Common uses of knots include: Maritime navigation and ship speed; Aviation airspeed and ground speed; Wind speed in marine forecasts; Ocean current measurements.

Here are some common values converted:

1 ft/s = 0.592483801296 kn 5 ft/s = 2.962419 kn 10 ft/s = 5.924838 kn 50 ft/s = 29.62419 kn 100 ft/s = 59.24838 kn
