How to Convert Feet per Second to Knots
To convert feet per second to knots, multiply the speed by the following conversion ratio: 0.5924838 knots/feet per second.
Since one feet per second is equal to 0.5924838 knots, you can use this simple formula to convert:
The speed in knots is equal to the speed in feet per second multiplied by 0.5924838.
For example, here's how to convert 5 feet per second to knots using the formula above.
How Many Knots Are in a Feet per Second?
There are 0.5924838 knots in a feet per second, which is why we use this value in the formula above.

Feet per Second and knots are both units used to measure speed. Keep reading to learn more about each unit.
What Is a Feet per Second?
A feet per second is a unit of speed equal to 0.3048 meters per second (m/s), the base unit for speed. Equal to 0.3048 m/s. [1]
The feet per second is classified as a US customary and imperial unit of speed. Feet per Second can be abbreviated as ft/s; for example, 1 feet per second can be written as 1 ft/s.
When working with feet per second (ft/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, feet per second (ft/s) are widely used across standard speed applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Knot?
A knot is a unit of speed equal to 0.5144444 meters per second (m/s), the base unit for speed. One nautical mile per hour (1.852 km/h = 0.514444 m/s). [2]
The knot is classified as a standard unit of speed. Knots can be abbreviated as kn; for example, 1 knot can be written as 1 kn.
When working with knots (kn) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, knots (kn) are widely used across standard speed applications within international standard workflows, engineering documentation, and technical data sheets.
When converting speed between feet per second (ft/s) and knots (kn), keep full floating-point precision (1 ft/s = 0.5924838 kn; 1 kn = 1.6878099 ft/s) during intermediate calculations and round only the final knot figure to match your instrument tolerance.
