Convert Feet per Second to Knots
ft/s to kn · speed conversion
What are feet per second and knots?
Feet per second is an imperial speed unit used in ballistics and some engineering. A knot is one nautical mile per hour (1.852 km/h), used in aviation and shipping. For reference: a brisk walk is about 5 km/h (3 mph), and highway speed is around 100 km/h (62 mph).
How to convert feet per second to knots
1 ft/s = 0.592484 kn. To convert, multiply the number of feet per second by 0.592484. For example, 5 ft/s = 2.96242 kn, and 20 ft/s = 11.8497 kn. To go the other way, multiply knots by 1.68781 (since 1 kn = 1.68781 ft/s).
