How to Convert Feet per Second to Knots

To convert a measurement in feet per second to a measurement in knots, multiply the speed by the following conversion ratio: 0.592484 knots/foot per second.

Since one foot per second is equal to 0.592484 knots, you can use this simple formula to convert:

knots = feet per second × 0.592484

The speed in knots is equal to the speed in feet per second multiplied by 0.592484.

For example, here's how to convert 5 feet per second to knots using the formula above.
knots = (5 ft/s × 0.592484) = 2.962419 kn

Feet per second and knots are both units used to measure speed. Calculate speed in feet per second or knots using our speed calculator or keep reading to learn more about each unit of measure.

What Are Feet per Second?

Feet per second are a measurement of speed expressing the distance traveled in feet in one second.

The foot per second is a US customary and imperial unit of speed. Feet per second can be abbreviated as ft/s, and are also sometimes abbreviated as ft/sec or fps. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[1] For example, ft/s is expressing a change in length or distance relative to a change in time.

Feet per second can be expressed using the formula:
vft/s = dft / tsec

The velocity in feet per second is equal to the distance in feet divided by time in seconds.

What Is a Knot?

One knot is equal to a speed of one nautical mile per hour,[2] or one minute of latitude per hour.

Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.
