Convert Feet per second to Knots
1 foot per second is 0.592484 kn. One foot per second is exactly 0.592483801296 knots.
One foot per second is 0.5924838 knots. To convert feet per second to knots, multiply by 0.5924838; to go the other way, divide by 0.5924838 or multiply by 1.6878099. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly 0.3048 m/s.

What are feet per second and knots?
- Foot per second (ft/s)
- Exactly 0.3048 m/s. Muzzle velocities, falling objects and anything where a foot is the natural length.
- Knot (kn)
- One nautical mile per hour — exactly 1,852 metres per hour. Used at sea and in the air because a nautical mile is one minute of latitude, which makes navigation arithmetic simple.
