Use this page to convert knots into feet per second. It is useful when nautical, aviation, or wind speeds need to be used in US customary engineering, motion, flow, or short-interval calculations.
Knots are nautical speed units; feet per second is a short-interval technical speed unit.
This conversion helps navigation data work in foot-based calculations.
Feet per second is useful when distance over seconds matters.
Knots remain clearer for pilots, sailors, vessels, charts, and marine forecasts.
The target unit should match the rest of the calculation.
This page converts speed only.
Knots are tied to nautical miles per hour.
Feet per second is tied to short-interval movement in a foot-based system.
The conversion is useful when navigation or weather speed data needs to be used in a US customary technical calculation.
A speed in knots can be hard to use directly in calculations measured by seconds.
Feet per second shows how far something moves each second.
That can help with motion analysis, flow estimates, impact calculations, or simulation work.
1 kn should be about 1.68781 ft/s.
10 kn should be about 16.8781 ft/s.
If 1 knot becomes 0.592484 ft/s, the conversion direction has been reversed.
Definition: A knot is a speed of one nautical mile per hour.
History/Origin: Knots are used in maritime navigation, aviation, weather reporting, sailing, and ocean-current measurement.
Current use: knot is used for boats, aircraft, wind forecasts, marine navigation, sailing, currents, and nautical-speed references.
Definition: Feet per second measures how many feet are traveled in one second.
History/Origin: Feet per second is used in US customary engineering, ballistics, fluid flow, motion analysis, and technical calculations.
Current use: fps is used for motion analysis, engineering, ballistics, flow rates, physics examples, impact speeds, and short-interval speed data.

Example: 15 kn = 25.317148 ft/s
Precision note: Use 1.6878098571 feet per second per knot. Keep precision for engineering calculations and round only for display.
One knot is about 1.6878098571 feet per second.
Feet per second is useful for short-interval motion and engineering calculations that use feet and seconds.
Usually yes for navigation. Convert to ft/s when the speed must be used in a technical calculation.
