Knot (kn)
The knot is used in marine and aviation navigation for ship, aircraft, and wind speed.
History: the knot is named after the knots on a ship log line once used to estimate speed at sea.
Quickly convert knots to feet per second without lookup tables or manual math.
This page is focused on converting knots to feet per second. Type a number into the first field and the result appears immediately in the second field.
Example: 1 kn = 1.6878098571 ft/s. Conversion formula: result = value × 0.51444444444444 / 0.3048.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.

The foot per second appears in ballistics, aerodynamics, and engineering calculations in imperial units.
History: feet per second developed as an engineering derived unit from the foot and second in imperial technical practice.
Enter a value in the Knot field. The converter applies the formula "result = value × 0.51444444444444 / 0.3048" and immediately shows the result in feet per second.
