Convert knot to foot/second
Please provide values below to convert knot [kt] to foot/second [ft/s], or Convert foot/second to knot.
1 kt = 1.68780985696 ft/s. To convert knot to foot/second, multiply the value by 1.68780985696; to go the other way, divide by it (1 ft/s = 0.592483801347 kt). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kt = 1.68780985696 ft/s

Knot
A knot is a unit of speed equal to one nautical mile per hour, commonly used in maritime and aviation contexts.
History/Origin
The knot originated from the practice of measuring a ship's speed using a device called a chip log, which involved counting the number of knots that passed through a sailor's hands over a specific time interval. It became standardized as a unit of speed in maritime navigation.
Current Use
Today, the knot is primarily used in maritime and aviation industries to express the speed of ships and aircraft, providing a consistent measurement across international waters and airspace.
Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
